These intolerable college kids just wanted a break from their studies! They just wanted to spend some time on a lake, taking their shirts off and engaging in forgettable dialogues that a screenwriter thought sounded just like how real people talk! They couldn't know there would be a 3-D shark in the water! Nor that the fish would sometimes linger behind them for a while before attacking, watching their nubile bodies bounce as if in slow motion, carefully assigning each young woman a mental score before physically tearing her apart with his powerful shark jaws. It turns out that's what happened, though (possibly):
How much better would this be if the shark had the voice of JB Smoove?
