It’s always good to be able to categorize and explain relationships in the world.
I’m going to have to ponder this further, though. The Mummy is clearly in the same region as Frankenstein, but does the infectious nature of lycanthropy put the Wolfman in the same category as Dracula? I guess if zombies count as converters, so do werewolves. Curiously, the modern monsters of slasher flicks, the Freddies, the Michael Myerses (no relation), the Jasons, seem to have avoided the converter/contagion element of other movie monsters.
