This movie didn't do well, and I really don't know why. Wikipedia says the critics said things like this.
"Though it sports a slick look and feel, Surrogates fails to capitalize on a promising premise, relying instead on mindless action and a poor script."
I couldn't agree less. The premise is intriguing, the action is exciting, the performers really perform, and the way the story presents the concept is downright creepy.
I mean, the whole idea of aging, overweight, unwashed people lying in darkened rooms while gizmos relay signals back and forth between their brains and the robot bodies they control remotely is both brilliant and disturbing.
The movie also does a great job of making Bruce Willis capable of playing his aging actual self as well as his youthful artificial body. Ditto for his wife, Rosamund Pike, who's gorgeous when she's a robot, but not so hot when she comes out of her dark bedroom and into the real world.
We get a good murder mystery with this one, too, and it was done in a nice hi-tech manner.
All in all, one hell of a good science fiction movie.
