the content of graphic sex and sexual violence and drug taking and murder be aim at an audience that want to be titillate and and in this modest aim donkey punch more or less succeed . yet somehow director oliver blackburn squanders reliable staple teen horror fare into an indigestible mess which be difficult to stomach . four young men and three young woman and party and have sex and and then become embroil in a deathfest when one of the girl die during a sex act . the acting be fairly good and the character be fine and the girl and sian breckin and nichola burley and jaime winston ( daughter of ray ) look good and be a teenage boys dream and well up for it . a setting on a boat always have dramatic potential and confine space and isolation and no escape . it also have some drawback and physically you be limit with what you can do . this be where blackburn errs . the first half hour of scene setting a the character get to know each other be fine and and the sex scene be convince . but once the bloodletting start everything spiral out of control . the action of the character be inconsistent at best and and unbelievable at bad . this be no psychological thriller and if you do not know what to do kill someone and that appear to be the maxim . each sequence be so episodic and so stand alone and that there appear to be little link with what else be go on . by the end the dramatic tension have evaporate and you just want everyone to die and but quickly . apparently this be shoot in 24 day and which be quick . but this be no excuse for an inadequate script and screenplay .
