Good movie. It went by quickly, too. That said I really dislike watching a film in 3D and I will avoid it whenever possible. It really bothers my eyes. If there are technical flaws to this film (and I'm sure there are) I didn't spot them. It really conveyed that sense of how messed up you could be in space with no gravity to anchor you. There were moments that really creeped me out. If there was a strain of credibility it was how anything that could go wrong pretty much did but, of course, thats dramatic licence. I give it an A.
