Let me start out by saying that nothing will ever, ever, and I do mean EVER top 'Lesbian Vampire Killers' for hysterical horror satire. But 'Killer Pad' just beat out 'Shaun of the Dead' for second place.
The humor in American horror satire is usually limited to slapstick, sight gags and pop-culture banter. Consequently it quickly becomes dated, and the humor loses its edge, leaving its audience to wander off in search of the next fix. 'Killer Pad' actually bothers with a script. The situational comedy is deftly arranged, so that the running jokes STAY funny, popping up in unexpected ways, and often the excuse to bring the gag up again is a gag in itself. The jokes don't need to be propped up by a backstory only one generation will really get; they're funny on their own. And likely to remain so!
The actors deserve equal credit for the comic success of the film. It's difficult to keep a character consistently, genuinely, believably oblivious for more than an hour, and to make the audience genuinely laugh at their idiocy instead of just rolling their eyes and getting bored. They achieve it, though. It's my favorite thing about this movie.
Those who come to 'Killer Pad' looking for shallow, cheap humor and obvious jokes will be disappointed, but for anyone seeking a fresh, fun spin on the "evil house" theme: you've found it. So sit back and enjoy!
