As far as Judge Dredd, my personal beef is that Megacity One's "dystopian" density with 800 million inhabitants from Boston to Washington DC barely ranks in terms of density in today's top 100 cities.

As far as Idiocracy, I believe that if the networks had played that and it was promoted on YouTube for free the night before the most recent presidential election, it might have gone differently.

What else would you add to the list?
