Its difficult to answer your question absolutely Kate.
May ones answer is coloured by ones own characteur?
One might answer 'Aliens' if you tended to be a little pessimistic. Prehaps 'Space Odessy' or Time machine' if a little optimistic?
Metropolis, smacks of Unionised heavy work, not for us humans, under a yoke.
But a very good film nevertheless. It reminds me a little of 'Modern Times' that starred Charlie Chaplin, that came much later, which had a lot of tongue in cheek comedy as well.
We need more people to vote, for a definate answer
