Aquaman IS Aquaman, an American mythos character who has been around for three quarters of a century. And while he isn't on the same tier as the Big DC Three, Aquaman has a rich comic book history all his own.
The Wonder Twins? lol. The twins were a by-product of hapless Saturday morning, childish marketing buffoonery. In some ways, the Scooby Gang was more maturely presented than the Super Friends concept. Heck, I would take Scrappy Doo over Gleek any day of the week and twice on Sunday.
Everything connected with the Super Friends era, except for each episode ending moral lesson, was an intellectual farce. Hopefully Hollywood will never be stupid enough to resurrect that mentality again. Then again, I do remember Howard the Duck appearing at the end of Guardians of The Galaxy. And I must remind myself that same type of utter nonsense inspires Hollywood improvisationalists like Ben Stiller and Will Ferrell.
