It's fast-paced, slick, lively, deliberately silly/comical, and certainly a lot less dumb than myriad recent horror spoofs like "Transylmania." Some aspects are broad, but others are slyly unexpected, like the villainess' seduction scene with yuppie jerk Charles, and her mute giant brother's feelings toward the camp yet resilient gay guy. It's a deliberately crass movie, yet it's got some wit, energy and invention, certainly more so than most recent low-budget U.S. slashers (or spoofs thereof). As a semi-guilty pleasure, I've watched it several times and quite enjoyed it every time. My favorite performer was Martin Bayfield, absolutely. He does a sympathetic Igor/Frankenstein "monster" act with considerable charm.
