Not OP, but to me it's one where getting to the ending gives you the context/lense to reinterpret the earlier portions. Sorta like memento or fight club, where the ending recontextualizes the earlier scenes.
I had to pause that movie several times on my first watching. Not because it was bad or anything, it was amazing, but because there was so much stuff going on at once. It's now one of my fave movies to recommend to people
