But those aren't meant to be serious shows and never were meant to be that. Who says they should be serious shows? They wouldn't work that way.
Super Hero Squad is just Avengers but made for little kids, and we'll be getting an Avengers cartoon in a couple of years anyway so it doesn't matter.
Batman Brave and the Bold is 50s/60s Batman after we've had some of the darker stories told recently (The Dark Knight, Batman TAS) so it's good to have a change and tell different stories the others couldn't tell.
Teen Titans, well if you take out all the comedy elements it's just got some dodgy characterisation, samey plots, uninteresting villains beyond Slade (who isn't that well characterised), and heroes who are too attached to their costumes. If this was a serious show it'd be a really bad one. Since it's a comedy those elements don't matter so long as it's funny.
