There's a disturbing number of people who watch movies like RoboCop and Starship Troopers and don't realize they are satire.

I have a running joke with my closest friends that we are in a post-satire world because real news today is frequently indistinguishable from satire from 10-20 years ago. Sometimes The Onion headlines just bleed into the monotony of the news cycle, but it's not because they are any less satirical.
