Donkey Punch (Oliver Blackburn, 2008)

You might call this low-budget Britflick a cautionary tale for the E-d up Ibiza generation. Alternatively, it's just another carbon copy of any other schlocker in which a bunch of young morons hedonise away until it all goes sour and turns into dog-eat-dog. And then there were none.
Blackburn's debut covers its bases against charges of implausibility of motive by having its characters stoked to the gills on pills and gives the viewer licence to moralise by making nearly all of them both amoral and unlikable. Unfortunately this also means that, when they start knocking each other off on their purloined pleasure boat with escalating levels of gore, you're hard pushed to care one jot.
