This movie is somehow a potpourri of different movies such as 2001, Gravity and Sunshine, but it luck their artistic sense. Sunshine with a very low budget has reached much better results and Gravity appears much more scientific and realistic. I am not even comparing it with 2001 of Kubrick. This movie is pointlessly too long, a little bit pathetic and the colors are very dull. The same greenish atmosphere that Nolan apparently loves so much. Definitely Christopher Nolan is overrated as a director. I cannot understand why. However, this movie is much better than the Dark Knight which in my opinion is the worst movie ever made.
