The car is not a bad film. It's not a good film either. The acting, direction, cinematography and music are solid. The problem lies with the plot which is neither interesting nor frightening. I won't belabor the point. You can skip this one altogether. Even veteran actors such as James Brolin and Ronny Cox cannot save this film from its lack of of excitement and originality. I expect greatness from Universal Studios. This one does not deliver the goods.
As a weird side note, Satanist Anton LaVey was the "creative consultant" for this film. Too bad they didn't speak to either John Carpenter or Stephen King instead!
