The new series tries to add depth to things that weren't there. It's not successful at first, but near the end of the first season and through season 2, Fred and Daphne really have some character development. Even Scooby-Doo has become kinda bad&$$. It really has taken an even darker turn, and they're heavily implying Scooby's going to betray the gang. Even the Venture Bros parody of the characters weren't that dark, and they based them off of famous serial killers.Yeah but at least he had some personality. I dunno...the new show he just seems like a moron with little to no personality. Actually, none of the characters have personality in the new show. They are all so flat...and I can't blame the voice actors because they are the same as What's New Scooby Doo with the exception of Shaggy.
But thinking back, they didn't really have much personality in the original show either.
But Fred never had personality, same with Daphne. To some extent Velma too. Pup turned them into parodies of themselves, and the show was all the better for it.
