I'd say the worst TV shows, IMO, is 4Kids' dubbed animes. I know, its not a TV show, but seriously, they have dubbed SO WRONG that there's a reason Funimation actually exists. 4Kids was just a stupid anime dubbing company who liked to make stuff for kids when in fact, ITS FOR TEENAGERS AND ADULTS SOMETIMES. (yes, Pokemon was for kids, but seriously, dubbing One Piece was one of 4Kids' dumbest decisions ever)
