This movie holds your interest and keeps you wondering, up until an ending which will make cry out "Oh boy!". It's so gruesome and far-fetched and off-base that it's positively ludicrous. On the plus side, Drew Barrymore burns up the screen with a much steamier performance than the one she gave in "Poison Ivy", and the "good guys" are unusually likable (in an unforced way) for a horror film.
