“Knucklebones” (0 stars out of four) was a dreadful horror thriller for knuckleheads about a group of bored and none-too-bright college students who unwittingly unleash a sinister force that begins murdering them after they play a game of dice with discarded bones. You can only wish that the script of this mess was discarded with as well. Terrible filmmaking and low-rent production turn this into a real horror show and the film is snail-paced and boring to boot. Re-caulk your bathtub instead.
