Oldboy

Absolutely peak film. I must have seen this nigh on 20 times and it never gets any less impressive. I'm certain you could take any single frame from its entire runtime and it'd be an iconic still. Every inch of the film has purpose, style and thought behind it, which is such a rare thing. The ending works so well because the cast absolutely nail every element of it. Choi Min-Sik has so much range in this one film alone it's almost inhuman. Incredibly grim, absolutely unforgettable. Also my most owned film by far. I think I've picked up every variant going at this point.
