Anybody here who hasn't seen Dark City... Just go see it, that's really the most imporrtant thing I can say on the subject.
Only seeing Matrix is like taking the blue pill.
Really, it's odd that the film just was so over-looked even before Matrix came out, given the cast is so much better.
In terms of the idea of copying, well that would be a further insult to Matrix if true, but I'm pretty sure that wasn't possible,
as Matrix would already have been planned if not in shooting and production before Dark City could have been released,
even if from viewer's perspective Dark City came out a year earlier so Matrix seemed like it was poor quality knock off.
This does make me remember there was director's cut Blu-Ray that was re-released and now I want to see it again
