I think Batman is on the same spot, complete with the preschool series.
But yeah, there's not really much in the way for action-oriented superhero cartoons. Most of the recent ones like Big Hero 6, Stretch Armstrong, Avengers Assemble, and Marvel's Spider-Man have wrapped up. Everything else is comedic or intended for smaller children. I think Young Justice and What If? are the only ones left, and the latter I'm not even THAT excited because it's still too derivative of the MCU.
Oh yeah. This show actually broke up the usual superhero fights with Spidey occasionally fighting regular crooks. I don't think recent superhero cartoons really do that much. The last one was maybe Beware the Batman, but I could be wrong.
I'm listening to this tonight. I can't wait!
