D J Caruso’s hectically incoherent thriller stars Shia LaBeouf and Michelle Monaghan as the victims of a terrorist conspiracy. They are confused about what’s happening, and so may you be.

The basic premise is that the two ordinary New Yorkers are at the mercy of a disembodied female voice that knows exactly what they are doing. It can even force them to do what they don’t want to. We’re being watched, folks, and manipulated too.

Hitchcock could have done all this much, much better. All Caruso can do is orchestrate pile upon pile of meaningless action sequences and suggest a top secret plan to overthrow the government. One presumes Muslims are involved, since the Americans have initially blown up a terrorist suspect in somewhere like Afghanistan and made a mess of a funeral ceremony.

Caruso, who made the better Disturbia, is also preoccupied with showing us how computers, cell phones and security cameras can make our lives hell. He posits that these inanimate objects can make bad mistakes.

Billy Bob Thornton and Rosario Dawson are the FBI agents trying to do something about it all, and they are distinctly better actors than the leads which is probably why they are killed in the end. But do we care? This is a disastrous mess.
