Very few movies have made me want to get up from my seat and leave the theater. This is one of them. And it’s not even Ashton Kutcher’s fault, though he’s an easy target – the “Dude, Where’s My Car?” dude asking to be taken seriously in a dramatic role. He plays a college student who goes back in time in hopes of reversing his wretched childhood. What he finds there is gratuitously disgusting: child molestation and brutal animal abuse, for starters. (Kutcher himself, in case you’re wondering, isn’t bad.) Amy Smart plays the childhood girlfriend he tries to save. Rated: R for violence, sexual content, language, brief drug use. Rating: 1 out of 4 stars.
