How is it that so many people making money off of zombies are just freely using George Romero's zombies (i.e., flesh-eating, rotting, shoot-'em-in-the-head type zombies, which didn't exist before Romero invented them) without having to pay him a royalty or something? And even if they don't, isn't it a little obnoxious? As a fan of Romero's movies, I never dreamed of ripping off his specific ideas, and I know I'm not the only one to invent my own variety of undead (which is what GR did himself). But many of these guys are just shameless about screwing George, and act like making money off his seminal idea is some kind of tribute, or protected as parody or something. It ain't right.
