Of-the-moment callback to 90s teen movies that's enjoyable and more or less the right amount of knowing, and successful in keeping you guessing about where it's going and just how dark it will turn (in the end, not that dark but still darker than most, at least for a while), although not entirely satisfying in how it reconciles its treatment of the trauma of teenage cruelty between its two main characters. Also reminded me a bit of Promising Young Woman (which so far has proved to have a bit of staying power in the memory incidentally) but with a much gentler touch.
