I Know What You Did Last Summer (2025) is a fine summer slasher with a much nastier bite than it's 90's predecessors. While it's characters pale in comparison to the original (which really stand out in recent viewings as being so well-rounded, well-written, real characters), the kills are nice, there are some fun call-backs (including a great gag about the original film's sequel as well as one of the best uses of a returning character in a legacy sequel), and it's a sleek, funny when it needs to be, tense when it should be slasher whodunit.
And that would be my review up until the third act of the film. IKWYDLS25 does some of the most surprising big swings ever seen in the modern landscape of the legacy sequel. I'm honestly shocked the studio even entertained this direction, let alone let the filmmakers go full steam ahead with it. This film does and says things about the current trend of legacy sequels that honestly kind of made me love it a little.
Go in for a fun, bloody ride and strap in for a bonkers final act that takes some real balls to pull off as well as they do, IMO.
