Audiences polled by CinemaScore gave the film an average grade of "A−" on an A+ to F scale.
Colin Covert of the Star Tribune gave the film four stars out of four and said that Spielberg's first venture into animation was his most delightful dose of pure entertainment since Raiders of the Lost Ark. Amy Biancolli of the San Francisco Chronicle wrote: "Such are the timeless joys of the books (and now the movie), this sparkling absurdity and knack for buckling swash under the worst of circumstances. The boy may have the world's strangest cowlick, but he sure can roll with the punches". Roger Ebert of Chicago Sun-Times gave the film three and a half stars out of four, calling it "an ambitious and lively caper, miles smarter than your average 3-D family film". He praised the setting of the film, stating its similarity to the original Tintin comic strips and was also pleased with the 3-D technology used in the film, saying that "Spielberg employed it as an enhancement to 2-D instead of an attention-grabbing gimmick".
Peter Travers of Rolling Stone also gave the film three and a half stars out of four and wrote: "The movie comes at you in a whoosh, like a volcano of creative ideas in full eruption. Presented as the first part of a trilogy produced by Spielberg and Peter Jackson, The Adventures of Tintin hits home for the kid in all of us who wants to bust out and run free". Kenneth Turan of Los Angeles Times said: "Think of The Adventures of Tintin as a song of innocence and experience, able to combine a sweet sense of childlike wonder and pureness of heart with the most worldly and sophisticated of modern technology. More than anything, it's just a whole lot of fun".
Richard Corliss of Time wrote: "Motion capture, which transforms actors into cartoon characters in a vividly animated landscape, is the technique Spielberg has been waiting for—the Christmas gift … that he's dreamed of since his movie childhood". Jordan Mintzer of The Hollywood Reporter was also very positive about the film, describing it as "a good ol' fashioned adventure flick that hearkens back to the filmmaker's action-packed, tongue-in-cheek swashbucklers of the 1980s. Steven Spielberg's The Adventures of Tintin: The Secret of the Unicorn is a visually dazzling adaptation". Comparing it with another film, Mintzer said Tintin has "an altogether more successful mocap experience than earlier efforts like The Polar Express".
Belgian newspaper Le Soir's film critics Daniel Couvreur and Nicolas Crousse called the film "a great popular adventure movie", stating "[the film's] enthusiasm and childhood spirit are unreservedly infectious". Le Figaro praised the film, considering it to be "crammed with action, humor and suspense". Leslie Felperin of Variety wrote: "Clearly rejuvenated by his collaboration with producer Peter Jackson, and blessed with a smart script and the best craftsmanship money can buy, Spielberg has fashioned a whiz-bang thrill ride that's largely faithful to the wholesome spirit of his source but still appealing to younger, Tintin-challenged auds".
La Libre Belgique was, however, a little less enthusiastic; its film critic Alain Lorfèvre called the film "a technical success, [with] a Tintin vivid as it should be [and] a somewhat excessive Haddock". The Guardian's Xan Brooks gave the film two stars out of five, stating: "While the big set pieces are often exuberantly handled, the human details are sorely wanting. How curious that Hergé achieved more expression with his use of ink-spot eyes and humble line drawings than a bank of computers and an army of animators were able to achieve". Blog Critics writer Ross Miller said: "Author Hergé's wonderfully bold and diverse array of characters are a mixed bag when it comes to how they've been translated to the big-screen" and that while the mystery might be "perfectly serviceable for film ... the execution of it at times feels languid and stodgy, like it's stumbling along from one eye-catching setpiece to the next". However, he summed it up as "an enjoyable watch with some spectacular set-pieces, lavish visuals and some fine motion-capture performances".
Tom McCarthy, the author of a study of the Tintin books, described Hollywood's treatment in this film of its characters and stories as "truly execrable", stating that it ignores the books' key idea of inauthenticity. The themes of fakeness and phoniness and counterfeit that drive many of the original plots are replaced in the film with messages that feel "as though we have wandered into a seminar on monetisation through self-empowerment … It's like making a biopic of Nietzsche that depicts him as a born-again Christian, or of Gandhi as a trigger-happy Rambo blasting his way through the Raj".
Steve Rose from The Guardian wrote about one of the film's major criticisms: that The Adventures of Tintin, much like The Polar Express, crossed into the uncanny valley, thereby rendering Tintin "too human and not human at all". Manohla Dargis, one of the chief critics of The New York Times, called the movie "a marvel of gee-wizardry and a night's entertainment that can feel like a lifetime". The simplicity of the comic strip, she wrote, is a crucial part of the success of Tintin, who is "an avatar for armchair adventurers". Dargis noted that Tintin's appearance in the film "resembled Hergé's creation, yet was eerily different as if, like Pinocchio, his transformation into human form had been prematurely interrupted". Another major fault in the film, Dargis opines, is how it is overworked; she writes that there is "hardly a moment of downtime, a chance to catch your breath or contemplate the tension between the animated Expressionism and the photo-realist flourishes". Nevertheless, she singles out some of the "interludes of cinematic delight", approving of the visual imagination employed within the movie's numerous exciting scenes.
The film was named in New York magazine's David Edelstein's Top 10 List for 2011. It was also included in HitFix's top 10 films of 2011.
