Despite a number of oddities, Sunshine is the best Science-Fiction movie in many years. Visually stunning, excellent music, and a story with a lot of personality despite being essentially a mish-mash of sci-fi topics already used in previous movies.
The commercial success of this movie is doomed due to the strange way in which distributors have handled it, with late and staggered releases and a marketing campaign that tells too much. People will love it, hate it, or be ambivalent, but I hope it will become a cult classic.
