In all honesty this is nothing special. Perhaps a lead actor with more personality might have pulled it off and for me the gay/lesbian element feels contrived just to be PC. I know that this will set me up to be thought of as sexist, or anti whatever. Not the case, they just act the parts badly.
This is what happens if you cannot decide to make porn or a horror movie...you end up with utterly crap! The opening scene looked great..and from that moment everything went downhill (the cliff side).
