I just saw the movie.
I thought it rocked! I though it had great acting, and was very well put together. A lot of people didn't like it because the camera work they used and the movie itself was one of those B rated ones - however, I thought that just added to the movie. You felt like you were right there, in the water, experiencing this with them.
I would recommend this movie most definitly! The only precaution I have is that there is a lot of camera movement - like with the waves and stuff - if you get sea sick, you might want to wait till it comes out on video so you can take a couple of breaks...I am still a little dizzy, lol.
