Danny Phantom feels like 1 of the few Hero's that was really underrated. I feel he would do good in the DC universe. Considering his powers and all. Impulse and Tarot from the adult comic section I guess, I've just started reading the first comic so I have no idea what I'm getting into but I heard some positive reviews on it.

As for canceled shows, why does DC keep making shows and canceling after a few seasons?

Static had 4, YJ i think had 3 right? GL had 2, Beware the batman had 2 and a few other amazing shows. I'll be surprised if The Flash makes it. As my dad said about the Flash from the 90's, it's not that it wasn't good, he said it was amazing, what the issue was was the time, it was the 90's when Hero's were coming to the stage kinda deal. So I'm guessing that's why Flash wasn't really known yet. And I mean that outside of the comic franchise idea. So far I've seen almost all (good) DC comic shows and loved them. Super Boy sucked. Didn't even try.
