Ok, I remember seeing this movie a really long time ago. It's about a couple whose boat wrecks or something off of an island. They go on the island and the girl gets taken. While trying to find her, he sees a man get skinned and carved in a shack and finds out the island is full of cannibalistic freaks. Their leader is a female mermaid kind of creature. They worship some huge sea creature and at the end of the movie the guy gets burned really bad and falls into the water with the mermaid thing who wants to breed with him...I don't remember anything else but I would really like to find that movie again. Anybody have any kind of clue?
