Dead Alive (1992)

  For once, the tag line isn't a lie.  This is probably one of the goriest films you'll ever see.  Not scary so much, but if you don't like gallons of fake blood and dozens of severed limbs you probably won't enjoy this film.

After his mother (Elizabeth Moody) is bitten by a Sumatran Rat-Monkey, Lionel (Timothy Balme) notices a marked change in her personality.  Specifically, her sudden demand for flesh.  She soon infects her nurse, some punk kids, and the local minister, putting a severe crimp in Lionel's would-be relationship with the local grocer girl, Paquita (Diana Penalver).  It's hard to tell a girl you like her when you're trying to keep the town from finding out that your mother has become a flesh-eating zombie.

This was before Peter Jackson got all classy with his literature adaptations.  This is not high-brow cinema, or even mainstream, really.  Just good old-fashioned splatter comedy.  Bon appetit!
