These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Some Anvils Need to Be Dropped: Fascism can arise anywhere, even in places that think they're immune to it. Never say "it can't happen here," because it can, and if you don't remain vigilant, it will.
The Man Is Sticking It To The Man: The film is now very popular with teachers to make their classes more interesting. This creates the unfortunate situation where one authority tells you to not listen to another authority.
The Woobie: Robert is rejected by all his peers, and the Wave is the only place where he can find acceptance and a sense of purpose. He doesn't take it well when he finds out that the whole thing was a Hitler Youth experiment, implying to him that the only thing he's good for is to become a fascist thug. (His Real Life counterpart got better, though.)
