I watched this movie the day it came out and i loved it. the ending was fine as well. I've found that this movie is a love it or a hate it movie. People hated the end; yet it made sense. People hated the way it was filming; the way it was filmed suited the story. People argued that you don't see enough of the monster; the story doesn't focus on the monster. there is an answer for all the things in the movie, people just didn't like the answers. If you do like your movie closing up all the loose ends, I'd suggest that you don't watch it but you are missing out on a hell of a lot.
