But when you get right down to it, the plot is essentially about a shark that likes to eat people at one particular beach. It doesn't sound like it will end up being considered one of the greatest films ever made, but it did. It is a nuts and bolts basic thriller, as a huge hurricane begins to batter the Florida coast, a daughter goes to check on her estranged father when he doesn't answer his phone. When she arrives at her childhood home, she discovers him unconscious in the crawlspace beneath their home, with a massive gash on his chest.
Director Alexandre Aja keeps most of the action in a space that our protagonists can't even stand up straight in, and so dark that you'll be kept squinting on the edge of your seat, trying to spot the gators before our heroes do.
