... but thankfully not very often.
If it hadn't been for the stylish opening sequence where a teenage schoolgirl, cigarette clenched between her teeth, bludgeons, blasts, and burns a convent full of nuns, and the amusing later scene when Adrienne Barbeau (still sleazily sexy in her fifties) roars through the same convent on a motorbike decapitating demon nuns as she goes (yes, it's the same character), I would have only given this one star. The rest in between is total crap.
The characters are irritating beyond belief: a bunch of jocks who deserved worse than being turned into demons with poor makeup; the most feeble bunch of satanists you can imagine, two women with big boobs, an effete gay so camp he's insulting to camp gays, and a squeaky voiced leader -okay, they are played for laughs, pity they weren't funny.
The only remotely interesting character is the first to be turned into a demon nun thus making her stop being interesting leaving no-one at all of the cast you wish wouldn't die.
Feeble makeup and gore effects. Stupid and pointless strobe lighting effects which make the demons look as if they're having a fit.
A twist end that is so obvious the moment the movie continues after the demons are dead.
Reviews of this dvd encouraged me to buy it. Please, don't make my mistake. This is a horror-comedy which fails completely at both.
