just watched sunshine. holy crap, what an awesome movie. if you like sci-fi films, definitely check this one out. the one flaw of the movie is that it detours from sci-fi into horror for a ltitle bit (but it ends in sci-fi). besides that, it's a friggin' amazing movie. the visuals were stunning and not overdone (major suspension of disbelief required).

I have no idea how I missed hearing about this until now (Netflix recommended it to me). Check the trailer:

There is an amazing scene which has a wonderful song playing in the background; listen if you like those slow instrumental movie songs:
