Stars Wars and Doctor Who both feature villains transparently based on Nazis, and I’m coming around to the idea that Doctor Who had the more socially useful model: Imperial officers / stormtroopers come off as evil but maybe kind of badass, tough at least, whereas Daleks more accurately portray fascists as stupid and cheap and just gratingly skin-crawlingly annoying.
The idea that something as obnoxious and ridiculous as a Dalek can also be dangerous and utterly evil is…a useful lesson.
