Reading through these reviews, I realized that everyone needs to take one large step back. The five star reviews claim it's the best movie of all time, which is certainly not true, and the one star reviews claim it to be one of the worst of all time, which is also not the case. Seeing this, I figured it was time for someone to be reasonable about this film. Here's the deal: this movie is no Citizen Kane, it's no 8 1/2, it's no The Godfather, heck, it's not even as good as Memento, Nolan's actual best film. That being said it's also not anywhere as near as bad as Troll 2.
This is a perfectly okay science-fiction drama from a pretty good director of popular blockbusters, but it certainly has problems. The sound mix is off, Ann Hathaway's character is underdeveloped, and the end twist can best be described as "Shamalayn-esque." It is a good movie, with some solid performances and pretty good action, as well as believable human drama, but in the end it merely accomplishes what Nolan set out to do, and that's to make an intelligent blockbuster. This being said, however, I think that people tend to confuse a movie that makes them think a little bit with high art, which this is not.
I am not a troll, nor a Nolan-hater, just a Nolan fan that knows this director can and has done much better movies.
