Very enjoyable movie
5th August 2012
As others have said, it draws upon ideas from earlier movies, most obviously The Matrix and Metropolis and several others too; but after over 100 years of movies is it even possible to come up with a totally original idea? I doubt it.
I am also reminded of an old role-playing game called Paranoia and the regime in North Korea.
By no means original, but highly enjoyable nonetheless.
