Actually better than I thought it would be. Apparently, the normal piranha is not as dangerous as its reputation, but here we have a kind of mutant variety. Two young people are eaten right away and set the stage for more and more fish delicacies down the road. The fear is keeping these things confined to a limited area and out of the ocean where they could create a gigantic imbalance ecologically, not to mention these things running rampant (swimming rampant?). This is one of the movies that rode on the back of the popularity of "Jaws." It does have some good suspense and some terrifying scenes, but it is another gratuitous gorefest. Perhaps a bit of communication by the military might have helped prevent the carnage. Anyway, it's worth a watch for those who get into the right spirit.
