Sunshine was released on Blu-ray yesterday. Netflix conveniently shipped it such that it would arrive yesterday, and I watched it last night. It is great. The third act is a little weak, and the disc interface is a lot less cutting-edge than it had been hyped up to be, but these things don't matter. The visuals are just incredible as are the sound and score. Despite its total lack of marketing and its meager release, I think this is destined to become a classic in the genre.
