I just finished watching this a couple of minutes ago, and man, I really liked it. I don't see why a lot of people said it was terrible. I thought it was really good. When it did its film festival run, I heard great things about it, but when it got nationally released, I heard a lot of people said it sucked. But I'm not affected by anybody else's opinion, so I rented it anyway. And am I glad I did. I think it's a great "edge of your seat," high tension movie. I really like how the camera occasionaly dipped under the water to give you a split second glimpse of what you most likely didn't want to see. I'll probably add this to my collection in the near future.
