This movie TERRORFIES me!!!!

I don't swim in the ocean. I haven't since the age of five. I don't even stand in the water at the beach above my knees. When I was five I watched Jaws for the first time and needles to say, it made an impression. So when I saw this trailer, I thought: "Oh yay, I never liked swimming in lakes anyway..." I can't see this movie though truthfully if I was drunk I think it would be hilarious. On second thought, maybe Ill take a chance. But somebody else see it first and tell me if it's really scary. Ok?
