3D movies mess with my eyes and give me a headache, so I can't stand them. I seem to be in the minority on that, though.
I agree, Akira Yamaoka's music is great. The music in Downpour was still really good, though, even though he didn't do it. I don't remember the name of the man that did it, but he does the music to Dexter.
I own soundtracks to 3, 4 and origins. I would like to get the one for Downpour, eventually too.
