Christian Slater and Stephen Dorff, the reigning princes of Hollywood schlock, join forces in this brain-dead adaptation of a popular video game. It opens with a scrolling expository title so long and involved I began to wonder if it was a gag, then Slater takes over as a detective of the paranormal who's nosing around a natural history museum full of Native American artifacts. Dorff plays the commander of the local ghostbusters, who race around in body armor and spray bullets at marauding reptilian bipeds. Uwe Boll directed. R, 96 min.
