Some really great, scary parts, some really slow parts. Somewhat unbelievable that some one who has never scuba dived before could change tanks underwater, etc.

There were a couple cheesy parts but it was much better than I had anticipated it to be. It was surprisingly not too bad.

It has intensity.. When they dropped in the cage to the floor of the ocean and they were almost or were attacked by the sharks it did make me jump or yell. So I felt it was acted well and effects were realistic. However I didn't like the ending. I was annoyed that she just hallucinated at the end. It was surprising but just ended. needed more. I was disappointed that her sis died

Decent cheesy thriller with a few good jump scares.
