I own the movie and have seen it twice already. But I have to say, it's not really as bad as some people are making it out to be, yet it's not a "great" movie. The first 30 minutes or so are indeed great, though. But that's about it. The science is horrible, the cast, in my opinion, was pretty badly chosen, and there were a bunch of unanswered questions.

Anyway, it remains a decent movie, nonetheless. I know a few people who 'loved' it with a passion myself.
