It's a very underrated movie. Every shot is magical. It really feels like Boyle took every opportunity to move away from the typical sci-fi conventions. This movie is a must see in Blu-Ray with a good home theater sound system. Underworld did the music and the sound design is fucking amazing with a lot of the sounds oscillating from left to right. I could go on and on about this film. Not to mention the script is fucking tightly written and explores so many themes.
