If you like maimings, this is the hour for you. We’re catching up on recent genre films to hit DVD, and this is a particularly nasty batch. Sure, there’s the relatively tame pleasures of Lucky McKee’s revenge thriller Red. But then there’s the twin evolutionary nightmare of Toby Wilkins’ Splinter – which stars a ruthless parasitic entity – and Mitchell Lichtenstein’s Teeth, a vagina-dentate horror-satire that might upset some squeamish male viewers with its ruthless disregard for penises. Most of all, though, there’s Belgian filmmaker Koen Mortier’s relentlessly depraved Ex-Drummer, a movie with far too many moral trespasses for one blurb to contain. Somewhere in there, we might even find time to tell you if the movies are any good or not.
