Excellent movie. I saw it at the New Zealand Film Festival. First few minutes I really disliked the film. The digital camera was not good at all (it seemed almost as thought it was shot on consumer grade digital video) and initially it seemed like the director was going for strange arty angles, and was just self-conscious about it. Then there is the completely excessive and unnecessary nude scene for the (admittedly attractive) female. But once they get out into the water, I was just caught up into the film. While the digital video look remained an irritation in the underwater sequences (which would have looked incredible), the whole story of these two people drifting in the water was incredible. Not a lot of actual full on scares, but a hell of a lot of intense suspense. Definitely worth seeing. I really am amazed at how they filmed it, though.
