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
One of my favorite things i caught in a second watch was a simple thing, but i really liked the little touch they did to drive home the different realities they jumped thru. Did you notice the music playing in the car when theyre talking? Its a country version of "absolutely" -madding crowd. It also explains why short round ends up quoting the lyrics when he tries to explain how weird reality has become. It's not just a funny call out, it fits.
I really liked that little touch. There are many like that, and the film is well worth rewatching to catch them
