There is too much violence in this film for Dove to award it the Dove Family-Edited Seal. Most all the violence is showing sharks attacking and eating people. Much of it is graphic in nature and parents should be cautioned. The movie has some good suspense and action. The scientists are involved in a fantastic research project to eliminate the affects of Alzheimer’s. Sharks don’t seem to diminish in brain function as they age and the scientists strive to get to the bottom of that phenomenon. In doing so, they make the sharks smarter and this leads to the problems they find themselves up against.
