It seemed like it was another Aliens movie but underwater. The storyline was all over the place.

It was not very original and not scary at all.

First of all the movie gives no explanations. It started with the main character Brushing her teeth deep in the ocean. I still have no clue what they were doing there, why they were there or even who knew they were down there. The movie was so predictable it was crazy. The creatures did not bother me, The unrealistic and almost animated creature at the end did.

The plot has holes larger than the Mariana Trench in which it's set. Some good visuals and decent acting are the only saving graces and they're not enough to offset the entirely poor writing and storytelling.
