Nolan fan here.
The only thing I liked about it was something what other people complained about - the music - strong and punchy. Characters made little sense, the story was hard to follow and boring - towards the end I gave up my hopes. Some people say they need to watch it again to understand it? If it was emotionally engaging - why not... but it was not and I almost feel offended with thought that I need to see it again because somebody failed to make it clear enough while having me there for 2.5h. Anybody who would be willing to see a boring presentation again? Not me! To me it’s pretty inconsistent (why the wife at the end of the movie does not have to wear the mask), etc... This film can be described with the words spoken by one of the character’s - it’s a paradox, you can’t understand it so do not even bother.
