I watched this movie with my bf and I thought it was a very white knuckle psychological thriller...some reviewers commented on the poor quality, but I thought the cinematography had a real 70s feel to it and captured a feeling you get down there, in those islands. It all seemed very plausible to me. At the end of this movie, I said to my bf 'I'm not going scuba diving and we're not getting a boat.':)
