It was not good....not good at all. I jumped the first time a shark came at them, but after that it was pretty boring and a little annoying cause the characters were so dumb. The only good part of the movie was the end where the shark grabbed Mandy Moore as she's going into the boat during the hallucination scene.

It took to long to tell the story.

It wasnt very exciting and the ending didnt say anything that happened. For example, if she ended up dying from the nitrous oxide.

Was very predictable.
