From what I gather, Teen Titans Go is going to be a pure comedy series. Remember in the old Teen Titans show, how all the action would suddenly stop and everyone would grow giant heads and they'd shout at each other for a few seconds?
So I figure the basic idea of the new show is going to be like watching just those parts for a half-hour. No action, no supervillains, no saving the world, just large-headed kids shouting at each other about who has to clean the dirty dishes or pick up their socks for 22 minutes plus commercials.
As for Beware the Batman - well, it could be good, but I'm not excited about it. It'll have to do a lot to win me over, considering Batman has always been one of my least-favorite characters ever (and my favorite Batman shows have always been the ones where they take things a little less seriously).
Especially coming after the "death" of my favorite superhero game, I'm really disappointed. YJ was one of the few shows I've been making it a point to watch at all. (Not just cartoons, shows in general)
