It's got some decent FX, but when Catherine Bell who plays a "Dr." specializing in deep ocean work (with FOUR degrees no less) says "The Atlantic is the deepest ocean in the world", lost me. Even a high school student who pays attention in science knows the Pacific (home of the deepest known part of Earth, the Mariana Trench), is the deepest ocean. And to top it off (at this point) they are in Miami, mention Ft. Pierce and say it's an all day drive. Ummm...Ft. Pierce is less than 2 hours north of Miami. And I don't know who is writing for this, but Lithuania is NOT landlocked!!!!!! Good grief, writers, get your s**t together on facts.
