Reception
On the review aggregator website Rotten Tomatoes, 90% of 40 critics' reviews are positive. The website's consensus reads: "Elevated by S.K. Dale's inventive direction and Megan Fox's committed performance, Till Death will part the viewer with all but the edge of their seat." Metacritic, which uses a weighted average, assigned the film a score of 66 out of 100, based on 5 critics, indicating "generally favorable" reviews.
Writing for The New York Times, Beatrice Loayza said that "this straightforward romp focuses its attention on its cunning and no-nonsense scream queen. And what Fox lacks in dramatic prowess, she makes up for in pure, wicked magnetism." In his review for Variety, Manuel Betancourt said that, "Even as the twists and turns get ever more preposterous ... Dale’s direction and Fox’s commitment go a long way toward making Till Death a glossy, entertaining lark." Waldemar Dalenogare Neto declared that the film works because of Fox and said that he hoped that because of the "positive repercussions she would look for better roles ... [this] is an interesting film for those who like thriller."
Fox's performance was singled out positively by online critics, including Scott Weinberg (Thrillist), who admired the "very strong lead performance from Megan Fox;" Julian Roman (MovieWeb), who said she "delivers her career best performance;" Chad Collins (Dread Central), who said, "Megan Fox is always a welcome horror star, a contemporary scream queen with more grit and grunge than most, and she's as good here as she's ever been;" and Lee McCoy (DrumDums), who said, "It's a welcome return to horror for Megan Fox after 11 years since the cult classic Jennifer's Body.
In a review for Common Sense Media, Jeffrey M. Anderson said that "after a shaky start, this taut, vicious horror/thriller crackles to life with a dark sense of logic, a harrowing depiction of mental and emotional abuse, and a woman's boundless strength... it ultimately makes more sense than any Saw-related deathtraps." The previously mentioned MovieWeb review called SK Dale's debut "brilliant" and said, "He nails the Hitchcockian aspects of the narrative." Tomris Laffly, of RogerEbert.com, called the film "undemanding, a little silly, but a thoroughly engrossing and handsomely paced edge-of-your-seat experience all the same."
