In the not-too-distant future, everyone has a robotic avatar that he sends out into the world, controlling it with his brainwaves from the safety of his own home. The premise for this sci-fi actioner makes sense for about four seconds, after which you begin to wonder why everyone on the planet would willingly become a shut-in, how the poor are supposed to shell out for these high-tech androids, etc. But it’s great news for Bruce Willis (as a detective investigating the first murder in years), Radha Mitchell (as his partner), and Rosamund Pike (as his wife), whose faces get digitally polished to a gleaming smoothness. Jonathan Mostow, who did the third Terminator movie, directed a pro forma script by Michael Ferris and John D. Brancato, who wrote the third and fourth. PG-13, 88 min.
