I like Kristen Stewart from her previous movies. I think she is a quality actor, and so I wanted to see this movie. It was not as scary as you might think. The monster was huge, but a little funny looking to me. Overall, I would give it a B-. Dialogue wasn't that great, and the majority of the movie is dark.. as in hard to see through the murky water. Some critics have said that it reminds them of Alien with Sigourney Weaver.. I didn't think it was anything like the Alien.
