Feeble attempt at a genre movie that shows no passion for horror, and comes across a formulaic cash-in. It's what happens when intelligent people make a dumb movie. They under-estimate the audience and end up with crud. The acting is sub-Hollyoaks, the plotting ludicrous and the gore-soaked finale shrill and pointless. Not only that, but the message of the movie seems to be, if you do drugs and have casual sex, you will come a sticky end, the kind of laboured moralising that went out with the ark. Reactionary, worthless, but worst of all, pretty darn dull. Oh, and all the characters are hateful. Try Knife in Water, Dead Calm, even Saps at Sea, for water-bound thrills.
