I enjoyed the movie a lot. I wouldn't say it's the film of the year or whatever, but I thought the movie did what it was supposed to do. The camera work didn't bother me since I don't get motion sickness. I found it frustrating at some points, but in a good way.

[spoilers]Yeah, at the end there you see something fall into the right side of the screen in the ocean. I swear to god I was the only person in my theater to notice this. Since it fell from the sky, I am going to assume whatever the hell the monster was came from space, and it can grow to it's state we saw in the movie in little less than a month. Scary.[/spoilers]
