Alicia Lutes of IGN gave the first season, a 8.4/10, stating that it is "so insane, you're bound to be riveted and engaged if nothing else" and that the series is "a horrifying love letter to all those romantic ideals and expectations that have permeated our society." Liz Miller from IndieWire gave the first season an "A−" grade, mentioning in a positive review, that it invokes "the best qualities of David Fincher's Gone Girl and Mary Harron's adaptation of American Psycho," and that the series "juxtaposes the idea of love as glamorized by the romance industrial complex with its dark side." Kylie Nixon from Stuff complimented the first season in her review by adding that the "show will mess with your head. You might feel super, super awkward a couple or fifty times, but by God, you'll be entertained."
Tiffany Kelly from Daily Dot recommended the first season in her review of the series by stating that it "quickly evolves into a disturbing profile of a psychopath in the digital age, one who uses social media to aid his stalking." While reviewing the first season, Anna Leszkiewicz from New Statesman declared in a positive review that "You does what it says on the tin – offering surprise twists, drip-fed reveals, a magnetic villain in Joe, the horrible suspense of knowing more than his clueless victims and satisfyingly gory murders." Christina Radish of Collider named Joe Goldberg as the "Best TV Villain" of 2018. Radish wrote that, "thanks to the performance given by Penn Badgley and some terrific writing, the character has layers that make him complicated and intriguing, even though you know he should be making you cringe and recoil. Joe Goldberg is a character that does horrible things, but also keeps you so engrossed that you can't stop watching."
