Loony in the Woods (2006)

Released by Troma in 2013 - on VHS - this is a British partial-spoof of slasher films. In a little more than an hour, there's a face pushed onto a barbecue grill, an arm chopped off, fireworks strapped to a head and ignited, impalement with eye gouged out, electrocution and a face flayed. The characters are just fodder for the killer, whose identity is revealed at the end; he wears a ski mask throughout the film and seeing him at the end means nothing. It's very slapdash and amusing in small doses.
