It’s kind of like Aliens, but with Mako Sharks. Experiments to use sharks in the search for cure for Alzheimer’s Disease goes horribly awry when two scientists (who have obviously never seen a science fiction movie before) decide to move things along by increasing the brain size of their subjects. Now, of course, the intelligence of the sharks has increased dramatically, and they’re plotting an escape, taking out as many of the humans as they can. First use of CGI sharks, and that aspect is impressive. The cast includes Saffron Burrows, Thomas Jane, Samuel L. Jackson and LL Cool J.
