Deep Blue Sea was nothing like Jaws. They should've stopped making them after two. Jaws 3 and 4 were terrible. Those two movies fall under, "The what was I thinking" category.
Yeah Universal was able to get away with calling it Jaws 5 though...but absolutely had nothing to do with the beach or anything Jaws like. A good movie though imo. Open Water was worthy of 3 stars.
