Critical response
Grey's Anatomy has been well received among critics. As of August 2023, the show holds an average score of 84% on Rotten Tomatoes. Emily St. James of The A.V. Club gave an insight on the series' overwhelming success and the lows, writing that the quality arc is "all over the place". She noted the steady build-up in the first season; the series skyrocketing into a phenomenon in the second season; the gradual dip in season three; and "some seriously bumpy moments" in the fourth season, which was interrupted by the writers' strike. St. James felt that the "climb begins again in season five". Samantha Highfill of Entertainment Weekly in a review wrote, "I believe the show's best season to date is season 2. Let me make it clear that I'm not saying seasons 3 through 9 were bad. In my opinion, there have only been a few lulls in the show's history, and most of them didn't last a full season." adding, "I still enjoy the show, and I'll honestly never stop watching. By any standards, Grey's Anatomy has been successful television, ranking highly in the ratings for nine seasons and entering the cultural lexicon via phrases as cloying yet catchy as 'McDreamy', the show has had its periods of being intensely irritating, and it has had its periods when it seems as if Shonda Rhimes has taken leave of her faculties, but it's also got an amazingly high batting average, particularly with every solid season that passes along in this second act of its run." The site lauded the show saying, "On average, it's been very good TV, filled with interesting, driven characters who run the gamut of professions within the show's hospital setting. It's been, by turns, a good soap, a good romantic comedy, a good medical drama, and a good interpersonal show about an unexpected workplace family."
The first season received positive reviews which steadily built up, with Gary Levin of USA Today calling Grey's Anatomy one of the top shows on television. The New York Daily News named Grey's Anatomy a "winner", and Newsday expressed a positive opinion by stating "You simply can't stop watching." The Washington Post's Tom Shales was critical of season one, finding it reminiscent of ER and commenting that "the show is much more a matter of commercial calculation than an honest attempt to try something fresh and different." Shortly after its initial airing, the Chicago Tribune's Maureen Ryan called Grey's Anatomy the new Friends (a concluded National Broadcasting Company (NBC) sitcom following the lives of a group of young adults, that for all of its 10-year run was in the top-5 for viewer ratings). The second season received high critical acclaim: top critics like Emily St. James of The A.V. Club called the show a "phenomenon", adding the show was "one of the best TV shows around", while Samantha Highfill of Entertainment Weekly later during the tenth season called the second "the show's best season to date". However, Kevin Carr of 7M Pictures opined that Grey's Anatomy is a mere combination of Scrubs, ER, Sex and the City and The Love Boat. It further garnered positive reviews: Christopher Monfette of IGN added "The second season of this medical drama expertly wove its signature elements of complex relationships, whimsical banter and challenging life-lessons; all to a montage-fetish, indie-rock soundtrack." Todd Gilchrist, also from IGN, called the season "terrific" adding, "Indeed, one of the best currently on television. While it remains to be seen what the creators do with it, now that it's become an outright event program, the season demonstrates that Rhimes and co. know what to do with the opportunities presented them. Whether you're male or female, this is the kind of entertainment that small-screen devotees and folks fed up with television need to see."
The title character of Grey's Anatomy, Meredith, has received both widespread critical acclaim and weary feedback by critics along the course of the show, with the development of the character garnering praise from majority critics. Earlier reactions for Meredith were mixed; in a 2006 review, Alessandra Stanley of The New York Times dubbed her "the heroine of Grey's Anatomy". A reviewer for BuddyTV praised the distinct uniqueness in the character calling Meredith an "unconventional heroine" adding that the character was "Neither black nor white but always ... wait for it ... many shades of grey." The reviewer went on to add that even in her lighter moments, she has still been "dark and twisty." The sentiment was shared by Glenn Diaz who remarked, "You gotta love Mer when she's gloomy." When Pompeo did not receive a nomination at the 61st Primetime Emmy Awards, for her work as Meredith, Mary McNamara of the Los Angeles Times suggested that Pompeo, "has worked very hard ... to make Meredith Grey an interesting character", and should have received a nomination. IGN's Monfette, less impressed by the character, criticized her storyline as "some bizarrely under-developed sub-plot about depression and giving Derek a season's worth of reconsidering to do." Robert Rorke of the New York Post was critical of Meredith's relationship with Derek Shepherd, writing: "She used to be the queen of the romantic dilemmas, but lately, she's been a little dopey, what with the endless 'McDreamy' soliloquies." The development of the character has received praise from critics. Reviewing the first part of the eighth season, TV Fanatic wrote: "this season belongs to Meredith Grey. She is the heart and soul of the show and has been outstanding. This is a character that used to be so dark and twisty and has now grown into a more mature woman. Ellen Pompeo has been at the top of her game this season." Rick Porter reviewing the episode "How to Save a Life" from the 11th season for Zap2it wrote, "Without Meredith, and without one of Pompeo's strongest performances in her long time on the show, 'How to Save a Life' would have run the risk of coming across as a baldly manipulative death episode, the likes of which the show has done several times before. He added "'How to Save a Life' may not be the ideal Emmy-submission episode for Ellen Pompeo, considering Meredith is off screen for more than half of it. But it's among the best work she's ever done on the show." Janalen Samson of BuddyTV lauded the Meredith's development throughout the series, saying "When one considers how this character has grown over eleven seasons, it really is amazing. Kudos to Ellen Pompeo for her fine work. She's actually done the impossible, because I actually care what happens to Meredith Grey." Reviewing the season 12 premiere, "Sledgehammer", critics including Alex Hawkins of the Western Gazette again highlighted Pompeo's being due for an Emmy Award.
The majority of the supporting cast of Grey's Anatomy have been well received as well, with the New York Post's Rorke deeming Stevens to be "the heart-and-soul" of Grey's Anatomy, whereas Eyder Peralta of the Houston Chronicle was critical of her character development, stating: "[She's] the reason I don't watch Grey's Anatomy anymore." Kelli Catana of The Huffington Post named Yang "the best damn character" and deemed "the Grey/Yang relationship the most true friendship on network television." Television Without Pity writer Lauren Shotwell claimed Yang is "the only one of these five [residents] that regularly acts like an actual doctor". Analyzing Alex Karev, Rachel Simon called him "underrated", and she pointed out that his personal growth never seems to get acknowledged, as "Alex has evolved, slowly and realistically, into a genuinely good person whose faults don't miraculously disappear, but take a backseat to much better qualities." Robert Bianco of USA Today said Dempsey has a "seemingly effortless way of humanizing Derek's 'dreamy' appeal with ego and vanity". His friendship with Mark Sloan has been well received. Victor Balta said "they've demonstrated an easy chemistry that makes for some of the great comic relief around Seattle Grace Hospital." Addison Montgomery was deemed "sassy and bright and interesting." TV Guide said of Walsh's stint on Grey's Anatomy that she "adds spice to an already hot show." Callie Torres, after having previously received mixed reviews, was praised for her bisexual storyline. Critics added that the character was anchored by stellar performances by Sara Ramirez. Lexie Grey, having initially been criticized, became a critics' favorite in the series. Alex Keen of The Trades wrote that Lexie's "presence and confidence have increased quite a bit ... and actress, Chyler Leigh, does a fantastic job of making this progression feel seamless. Since the series has defused the tension between Little Grey and Big Grey (aka Meredith), Lexie has clear sailing through the season and steals the show as one of the best current characters on the series."
With the departure of several cast members throughout the seasons, many new characters have been added to the drama's ensemble. McKidd and Capshaw were referred to as "fresh additions" to the series, by Monfette of IGN. Matt Roush of TV Guide commented: "Hunt is the most encouraging thing to happen to Grey's Anatomy in quite a while." Matt Mitovich of TV Guide noted that Robbins "quickly established herself as a fan favorite", describing her as "a breath of fresh air in the often-angsty halls of Seattle Grace. On April Kepner and Jackson Avery, Courtney Morrison of TVFanatic wrote, "April has grown since her character was introduced ... she's honest. A girl with principles is a girl you want to do well." He described her and Avery as "a couple for whom viewers can root". Speaking of the new cast members, in addition to the remaining original ones, Robert Bianco from USA Today called them the show's "best ensemble in years".
Regarding season 3, Bill Carter of The New York Times called Grey's Anatomy "television's hottest show", adding: "[No show] is expected to challenge Grey's Anatomy for prime-time pre-eminence." Contrasting with Carter's view, Monfette of IGN said that it speedily found itself "mired in the annoying and absurd", adding: "This third season may very well represent a case of over-writing a concept that has, perhaps tragically, run bone-dry on narrative fuel." At the conclusion of season 3, Entertainment Weekly's Gregory Kirschling said "the show lacked a defining happy, warm-gooseflesh moment", adding that the season "didn't leave you dying for the [next] season premiere". Speaking of the fourth season, Laura Burrows of IGN said the series became "a little more than mediocre, but less than fantastic", adding: "This season proved that even strong chemistry and good acting cannot save a show that suffers from the inevitable recycled plot."
In contrast to the moderately negative feedback the third and fourth seasons received, Alan Sepinwall of The Star-Ledger said of the fifth season: "Overall, it feels more like the good old days than Grey's Anatomy has in a long time." Misha Davenport from the Chicago Sun-Times said season 5 "hits on all the things the show does so well", adding: "There is romance, heartbreak, humor and a few moments that will move fans to tears." Brian Lowry of Variety, less impressed, opinionated that the season 5 displayed the show running out of storylines. Speaking of the sixth season, Bianco of USA Today wrote: "Grey's has always loved grand gestures. You like them or you don't; the only real question is whether the show pulls them off or it doesn't. This year, it did."
The series has a score of 66 out of 100 on Metacritic, based on five reviews for season 7. In response to the season, Bianco from USA Today commented: "Happily, it now seems to have landed on solid ground." Also of the seventh season, Entertainment Weekly's Jennifer Armstrong said: "It's in the shooting's emotional reverberations that the show is regenerating after the past few hit-and-miss seasons," whereas Verne Gay of Newsday commented: "Unfortunately, they've settled on far-too-easy and facile answers for the most part." HitFix gave a positive review saying that, "season 7 overall has been one of the show's strongest ever." and added, "There was a time when Grey's Anatomy was this show where I suffered through a lot of stuff that made me cringe to get to those genius melodrama moments it could do so well. Over the last couple of years, it's evolved into a show that's much more consistent in tone, where it may not move me as often as it did in the early years but also very rarely makes me question my reasons for watching." Speaking of season 8, Entertainment Weekly's Mandi Bierly called it a "so-so season", and Lesley Goldberg of The Hollywood Reporter called it "emotional". Also acknowledging the fan base, Verne Gay of Newsday wrote "Grey's has had a good season and has an intensely loyal fan base to prove it" regarding the eighth season.
The ninth season received positive reviews, with Rob Salem of Toronto Star calling it "a solid return to form." Praising the friendship between Meredith and Cristina of Entertainment Weekly wrote, "There's still one good reason to keep watching: Where else can you find such deep friendships between female co-workers". The tenth season was also marked with praise, with Annie Barrett for Entertainment Weekly writing "There's true sorrow here along with the passion, which keeps their dynamic so intriguing to me." Caroline Siede from The A.V. Club wrote in her review for the tenth season "At its best, Grey's Anatomy is about everyday bravery, sacrifice, and courage. At its worst, it's a melodramatic, moralizing soap opera. Both sides are on display as the show heads confidently into its 10th season." Many sources, including Rachel Simon of Bustle and Nicole Pomarico of Wetpaint, claimed that Sandra Oh's performance during her final season on Grey's Anatomy is worthy of an Emmy nomination.
Bryce Olin of Netflix ranked Grey's 9th among the 50 Best TV Shows on Netflix stating, "It's a tough call, but based on Grey's casting choices and revolutionary portrayals of female doctors in the series, I'm willing to argue that Grey's Anatomy is the best medical drama of all time. Obviously, Shonda Rhimes didn't reinvent the wheel with the series, but there's no denying its popularity." adding, "I understand its significance in the pop culture sphere." He also stated that the show could go higher in the ranks with the upcoming season stating, "Apparently, Grey's Anatomy fans are passionate about their show, although it seems like they've been closeted for the last few years. I'd love to move Grey's Anatomy even higher on the ranking, but I'll have wait until the eleventh season comes to Netflix."
The show was criticized for its handling of a controversy: the Grey's Anatomy scandal revolved around actor Isaiah Washington using a homophobic slur on set. Mainstream media coverage scapegoated this scandal as "black masculinity for perpetrating homophobia, thus containing both sexual and racial difference in the name of tolerance."
Critics included Grey's Anatomy in top ten lists for five of its 14 seasons; these are listed below in order of rank.
