I've been a little curious to see this one for a long time, and after finally getting to see it.... it's one of the most puzzling movies I've seen.

The dialogue is nearly incomprehensible. In watching material like Shaun of the Dead, I usually get used to accents after a short time, but with this one, it started reasonably understandable, but by around halfway through it, I started having a very hard time.

Far too much time is spent setting the scenario up. Once the girl dies, the movie feels like it should be over. The drama that ensues feels absurd to me. I can understand that some people are able to take control of others pretty effectively, but the lack of opposition seems to be unbelievable.

People start making decisions that don't make much sense. I think that the girls would have both realized that they shouldn't light a signal flare if they don't want the people nearby to notice.

The deaths get stranger as the movie progresses. One guy dies by a knife, and that's handled well. Then someone dies by having a flare fired into his chest, then it ignites him on fire? Then someone dies by some tool - it resembled a weed wacker, but I'm not sure what it was. That one seemed particularly strange, but made all the more strange by how the killer had no motivation to kill.

The movie is otherwise competently made. The poor lighting out on a boat in the middle of the night is understandable. I can't evaluate the script since it was impossible to understand.

With some editing and general re-shaping of the story, the movie could be a nice teen thriller. But as it stands, it's not much more than a curiosity.
