"Girl House" has been called a slasher film for the digital age. The theme was done to death before the turn of the Millennium, though here there is a new twist, a couple of dudes are watching the carnage live on-line but are unable to warn the victims as one by one they are done to death by a disgruntled weirdo who has been driven into a frenzy by a cruel joke. Actually, it wasn't that cruel, but stranger things have happened in real life. In March 2014, a woman was given a 12 year sentence at Snaresbrook Crown Court after throwing acid in the face of a former friend. Mary Konye went to incredible lengths, disguising herself as an Orthodox Moslem woman, totally veiled, tailed her victim from the Underground station, and then attacked her. The motive was a throwaway remark that most people would have forgotten within a day or two if not an hour or two. Here it is not a remark but a caption on a photograph that unhinges a guy who although clearly highly intelligent is not exactly good looking, and is somewhat lacking in social skills, not to mention short tempered.
Okay, this dude is not just mad, he's insane because there are better things to do with a houseful of nubile young things than murder them, but if this tale has a moral it is never be unkind to anyone, even by accident. Or alternatively, once you knock the bad guy down with a golf club or a hockey stick, hit him again, and again, and again, and again...
