Really awesome movie. It's kite hard to understand at first and will require 1 or 2 rewatches to pick it up.

It's the kind of movie that doesn't hold spectator's hand to explain what's happening, but it's also not the kind of movie that messes up and nothing makes sense. All the info we need is presented, just not on a clear way. Some ppl may even need to do some research on physics concepts, entropy, etc.
