From the reviews I'm reading, you have to watch this film more than once to truly appreciate it. So for a first watch, I didn't enjoy it. I spent far too much time trying to understand everything that was happening - and that's a hell of a lot! - and trying to link the characters together - because the story obviously had to come together somehow - that I couldn't see what people love about it. It's a complicated film, so now that I understand it's premise I may have to rewatch to see if I can enjoy it.
