I've seen Metropolis, but not Things To Come - which has now been added to my Netflix queue, currently at ~300. So yeah, it will be a while before I see it. :P

Agree wrt the timing of the release of the film, and the message contained within - I have said before, and I will say it again, that humanity as a whole needs to grow up a LOT if we're ever going to make it "off planet" in some form or another.
