The episode was directed by Sophia Takal from a script she co-wrote with Adam Gaines and it stars Suki Waterhouse, Carly Chaikin, Kirby Howell-Baptiste, and Melissa Bergland.

Later, Alexis returns to her house to prepare for a New Year's Eve party with her high school friends Kayla, Chloe, and Danielle.

Danielle and Chloe lock Alexis and Kayla inside a sauna, intending to wait until they die before calling the cops to make the deaths seem accidental.

[2] Simultaneously with the announcement of the director, it was confirmed that the episode would star Suki Waterhouse, Carly Chaikin, Kirby Howell-Baptiste, and Melissa Bergland.

The website's critical consensus reads, "Though it starts slowly, "New Year, New You" builds into a twisty, chilling narrative that will please horror fans and millennials alike.

"[8] In a similarly favorable analysis, Bloody Disgusting's Daniel Kurland awarded the episode four skulls out of five and commended it declaring, "It’s a chilling story that only gets darker and more complex as it goes on.

"[9] In an additional acclamatory critique, Laughing Place's Mike Mack was equally approving saying, "If there’s one thing Blumhouse has done well with Into the Dark, it’s building suspense.

"[11] In a separate complimentary evaluation, Decider's Jade Budowski lauded the episode saying, "Takal deftly integrates themes of toxic self-care culture and the often-volatile nature of female friendships, and tosses in some biting satire and terrifying twists and turns for good measure.

"[12] In a more mixed assessment, RogerEbert.com's Brian Tallerico gave the episode a rating of 2 ½ stars out of 4 and said, "Sadly, like so many independent horror movies, the climax of "New Year, New You" falters.

It's clunky both in concept and execution, and then followed by a cheap stinger that will make the film dissipate from memory more quickly than if it had really landed its punch.

"[13] In an outright negative appraisal, Paste's Jacob Oller criticized the episode saying, "Takal's directorial ability may keep "New Year, New You" from being the worst Into the Dark yet, but the dull tropes, scene-chomping acting, and hole-riddled plotting at its core are resolutely rotten.
