Moritz and Pavun Shetty of Original Film serving as executive producers and Shay Hatten writing the pilot. On October 14, 2020, Amazon gave the project a series order, and it was announced that Sara Goodman had replaced Hatten as series writer. It was also announced that Goodman and Hatten would serve as executive producers on the series, alongside Erik Feig of Original Film and Rob Hackett, Michael Clear, and James Wan of Atomic Monster. On December 9, 2020, Craig William Macneill was announced as the director of the pilot as well as an executive producer. On January 11, 2021, Madison Iseman, Brianne Tju, Ezekiel Goodman, Ashley Moore, Sebastian Amoruso, Fiona Rene, Cassie Beck, Brooke Bloom, and Bill Heck were cast in starring roles. Later that month, Sonya Balmores was cast in a recurring role. In the following two months, Spencer Sutherland and Chrissie Fit also joined the cast in a recurring capacity.

Reception

The review aggregator website Rotten Tomatoes reports a 41% approval rating with an average rating of 5.3 out of 10 based on 46 critic reviews. The website's critics consensus reads, "A bloodless slasher that fails to congeal, I Know What You Did Last Summer's killer cast can't make up for the show's many plot holes and unsatisfying twists." Metacritic, which uses a weighted average, assigned a score of 45 out of 100 based on 14 critics, indicating "mixed or average reviews".

Meagan Navarro, writing for Bloody Disgusting, gave the series three out of five stars. Navarro wrote, "Fantastic deaths and a gripping murder mystery pull you in, even when its mostly unlikeable leads tend to polarize", adding, "The more the series progresses, the murkier things get. It succeeds wholly in ensuring an unpredictable mystery that continues to surprise. When you think you've nailed a reveal, the series makes a shocking left turn", and concluded writing that "They may not engender themselves well to the viewer, but the slow trickle truth of who they are and their many secrets makes for a propulsive watch all the same."

Daniel Fienberg, writing for The Hollywood Reporter, said that, unlike the films, the then-teenagers are users of Instagram, and that "it is only somewhat about Instagram, on a purely practical level, but it takes the myopia exhibited in previous versions of the story to an extreme". He added that while a "new take absolutely has an angle all its own, and a justification for retelling this story", it is "mediocre", and concluded saying there is something "amusingly subversive" about the "kills" that define the genre.

Aedan Juvet of Screen Rant praised the adaptation and its use of "next-gen scream queen" Tju, writing that the actor brings "laughs, screams, and sheer perfection to her role as the series' all-important character".
