Men always have their toys:
I would posit that Robocop is even closer to reality. Corporations taking over government. Omnipresent dumbed-down media for mass consumption (the tag line for the "news" show was something like, "give us 30 seconds, we'll give you the world"). Nice suburbs. Decaying big cities where taxpayers were left to fend for themselves and criminals do as they please.I have quickly skimmed this list of futuristic movies.
For me the best (I mean the most accurate) futuristic movie is Demolition man (1993).
I have not seen Idiocracy. This movie is based on the fact that the IQ has reached a top and now is dropping down with the new generations.
