Quite good for what it is

Overall, this mixture of bad movie making, bloody horror, crap fx and boobs (and other genitalia) make for some for remarkably satisfying brainless popcorn entertainment.

Shame about the crew

Perfectly adequate in it's display of deep water fear and claustrophobia, but making all members chagrined assholes probably wasn't the best way to make me care.

A but uninspired

Right from the start it quite mundanely runs by -=scary scenes=-. Then the science team moves in, after which the scares are pretty much gone. The boy's trick of constantly turning his head toward a scary event VERY SLOWLY was also getting on my nerves. DeWitt rose above it all.

Engrossing and impressive

A thrilling and chilling story with powerful footage and acting, shot in very smooth 3D. It didn't completely knock me down, but I am not yet sure why.

Evolves into something good

What starts of somewhat doubtfully as yet more mockumentary by cute rapping teenagers, gradually evolves into a rather dark, vile, nasty and scary movie indeed. It's slow pacing and lack of gore/fx only make it stronger.
