Eventually, the luchadores had defeated every conceivable threat and the genre petered out, because no one wanted to watch El Santo Versus Weakening Eyesight And The Doctor Who Says He Should Stop Clotheslining People For The Sake Of His Heart. But we'll always have the beautiful memories.
White People Playing Native Americans Killing White People
America has a long and terrible history of exploiting Native Americans, and Hollywood is no exception. Once early plots evolved beyond "Hey, here's a horse," Native Americans quickly became the savage villains in Hollywood Westerns. Eventually, movies turned a more sympathetic eye toward them, but there was a weird period in between during which filmmakers didn't know what to do. They'd overworked the "Natives as evil" angle, but directors still couldn't imagine one working at a restaurant or shopping at Whole Foods, what with all their mandatory war paint and ornamental headdresses. That confusion birthed Redsploitation.
A typical Redsploitation film begins with a Native American protagonist being abused by whitey, and ends with our hero scalping and tomahawking those assholes in the most stomach-churning ways possible. Think Inglorious Basterds, but without all the subtlety. Of course, all of our Native heroes were portrayed by white people, in case you were worried Hollywood did something right.
In the not-quite-classic Thunder Warrior trilogy, for example, Thunder returns home from a long absence, only to discover construction workers tearing up his ancestral burial grounds so they can build an ... observatory? You know those damnable astronomers and their cultural insensitivity. Thunder initially tries to defuse the situation with words, but the construction workers laugh him off and beat him up a bit, 'cause whitey gotta white. So Thunder breaks into a store, walks right past the guns, and grabs a big-ass crossbow, 'cause Natives gotta Native. Thunder subsequently murders everyone in town for three straight movies, like Rambo with better hair.
