We're just growing up. Yeah, some cartoons are stupid, but I'm betting if you to talk to a kid who's like age 5-8, or even younger maybe, they'd pry like those shows. :/ But see, we're all teens.
Yeah, names are getting odd..but then again, when aren't they? We're also used to anime, and anime comes from Japan, we're dealing with American shows here in the USA. <_<
So yeah, it's just we're growing up. I'd bet if you were to watch those shows you'd watched when you were younger you'd think they were stupid mainly because you've [hopefully] grown up.
