Coma
This film keeps you on the edge of your seat; it reminds me of Thesis, but I liked Thesis much more. The tension is palpable throughout, and the final climax is good, but I think it has pacing issues. It's an interesting watch, and the whole thing about the organization that keeps them hanging is really cool, but maybe it's missing something and there's too much footage. However, it's not bad at all.
