Set in a futuristic world where humans live in isolation and interact through surrogate robots, a cop is forced to leave his home for the first time in years in order to investigate the murders of others' surrogates.
Surrogates stays afloat by not taking itself too seriously, but also by recognizing that a movie about robots shouldn't look as if it were made by one.
The questions the movie raises have less to do with science than movie execution: Do the actors sound so robotic because they are playing robots well or humans badly? And did a machine write this dialogue? If so, could we please apply for an upgrade?
