This movie is clearly low-budget, which is obvious in the final product. But cheap movies can be entertaining. Not this one. It tries to paint everyone as a sinner, but makes virtually every character so loathsome that you want to cheer on the killer. But the killer is just a sad zealot with a crossbow and the most terrifying lateral lisp on celluloid. He's not funny, or intriguing nor interesting, and he has a sidekick who has even less personality. There's no logic to any of it, and characters flip sides on a dime without reason.
The one decent character (and actress) is the one who plays the older sister, but by the time she gets involved, the viewer is too numb to care. It's literally sex and drugs and profanity, but no plot or skill. There's a character who is supposed to be an ex-con and who talks like every member of a cheap prison flick, but who looks like a middle-aged accountant. It's actually jatrring to hear him speak.
The ending is completely predictable, but then, so is the rest of the movie. Why this was made is puzzling; why it was released is baffling.
