It's not supposed to be taken seriously, and that is great. It's not as /dark/ as the original Teen Titans tvshow (or most of DC tvshows, to be honest) but it's silly and funny and that was probably the point. It's a great silly show that makes you laugh. There's nothing wrong with that.
I think this show is funny. Obviously it isn't really about superhero stuff, it's about super powered being pulling off greater and greater crimes with no consequences. Don't watch this expecting teen titans or young justice and you will probably like it.
Oh yeah TTG definitely remind me of the Powerpuff Girls at times. It's funny though, 'cause Raven and Bubbles are voiced by the same actress. As for the TTG itself, it's not that bad overall. And most importantly, at least here BB/Rae is a thing. Well, sort of.
It wasn't really anything worth one's time.
