Well maybe not thought of as a "bad" movie. more obscure, but you may want to check out the '72 TV movie EVIL ROY SLADE (My late brother's favorite movie). A story of an orphaned child that even the wolves wouldn't raise. So he grows up to become the meanest villain in the west and it is left to retired lawman Bing Bell (Is someone at the door?) to come out of retirement and stop evil Roy and his villainy. It is thought that it had a part in inspiring the movie BLAZING SADDLES. Evil Roy Slade, the original HAVOC. Hilarious movie if you like it's kind of humor!!!
