Music didn't click with me. Too many inobscurable moments. So much that it almost put me to sleep. The comic relief was noteworthy and much appreciated. Kristen Stewart's performance was great.

It's a nice little thrill for a PG-13 film. Not enough for me to see it as a blockbuster film, but decent enough, with the customers.

Though the movie was exciting, I am not the biggest fan of sci-fi horror. It was an interesting storyline and the acting was good.

It's hard to show everything in a movie where part happens in total darkness. The monster in this movie seemed more like an alien and some parts seemed rather disjointed. There seemed to be little effort to give the characters any back story.
