Without a doubt Superfriends were the dumbest cartoons ever. It was no wonder because Hanna Barbera created it as a Scooby Doo clone with the Justice League. Sure Wendy was barely tolerable but Marvin and Wonder Dog? Marvin was barely a teenager but he's a total retard with that big stupid M on his shirt. It is a wonder that he was not killed in school. As for the Superfriends they had the dumbest villians and had the dumbest cases ever. From Dr Goodfellow to King Plasto watching this show was like hitting your head with a hammer. Thank God this travesty lasted only one season then they wisely retooled it but it was still barely watchable.
