Really freaking good. I loved almost everything about this film. The editing made it really easy to follow even while constantly swapping between the past and present. The only thing I'd criticize is the music. Maybe it's just because I'm used to hearing an epic soundtrack in a Nolan movie. I don't think that this film's soundtrack is offensive but it just didn't stand out to me. The only reason I point it out at all is because everything else was spectacular. Instantly became one of my favorite movies.
