The idea is brilliant, but the execution less so. It feels like Mostow and his writers have jumped in head first with little idea of what they actually planned to achieve. The film has a lot of potential but seems to fall short just when it could get interesting. It is also rife with plot holes.
The cast all do well and are different enough from their robotic selves to give due credit. Rosamund Pike in particular is subtle in her changes and a joy to watch. Credit also due to the costume and make up department for making the surrogates suitably plastic and perfect. I wanted so much more from this film. Pity it didn't deliver.
