I Know What You Did Last Summer (2021) [Season 1, Episode 1]
It's Thursday
Shown 15th October 2021
The book was set in California, while the 1997 movie was set in North Carolina. This version takes place in Hawaii, although it does not use the local scenery as much as Hawaii 50.
Madison Iseman is traumatised by some buried trauma. Worse, when she returns home she discovers someone has written I Know What You Did Last Summer on her wall in fresh blood.
We then get an extended flashback to the relevant events in the previous summer. It turns out that Madison plays twin sisters. The bisexual one is Lennon, while her straight sister is Ally (short for Alison). They party with their racially diverse friends, while the helicopter parents supervise them from the kitchen. When five of the teenagers head off for a drive, they end up in a road traffic accident with a pedestrian. They assume the pedestrian is dead, because they let a drunken teenage girl check for a pulse. Then they try to hide the body, getting spotted by at least one stranger.
This is all a setup for the rest of the show, and it actually looks quite watchable. Lots of questions are asked, and the audience's curiosity should be engaged.
