Same here. TV just isn't the same. I have at least three shows I keep up with, but that's it. Young Justice is really amazing. I'd probably even say it's just as good, if not, better than Justice League. Avengers on the other hand, pretty good, the character designs really remind me of Justice League but sadly, it's gonna end. They're gonna replace it with a new Avengers cartoons that's closer to the movie incarnation that can tie in with Ultimate Spider-Man... Supposedly EMH was always planned out to be 2 seasons because they already told the stories they wanted too.
Dude, it's a child's show, end of story. You don't need to justify anything. Everything you described to me is pretty much common sense to me and should be to anyone else my age. If there's people my age and older, actually learning from a kid's show, then they have serious issues.
