Recommend me one animated superhero series please! I'm not a 16 year old (25, actually), so no heavily kid oriented stuff. Internal consistency, smart stories, etc are plus.
There's a lot of "kid-oriented stuff" out there that's very smart, consistent, and high in quality. Lots of children are smart, or have the potential to be, so they can appreciate and benefit from smart, well-made, challenging storytelling as well as adults can. Not to mention that children's parents should ideally watch TV along with them, so good children's shows should have appeal for adults as well. Not to mention that the people
making the shows are adults and they want to be able to enjoy and take pride in their work.
The gist of all this is that there are a lot of "kids' shows" out there which are very smart and satisfying for adults -- often smarter than a lot of the so-called "adult" shows out there. So you might be missing out if you assume kid-oriented shows can't be intelligent enough for you. Heck, I'm over 40, and a lot of my favorite shows are nominally aimed at preteens. If you set your standards too narrowly, you may cheat yourself out of a lot of enjoyment.
I'd pretty much agree with all of
Kelthaz's first four recommendations, except with the clarification that
Teen Titans was blatantly not a DC Animated Universe show, but was set in a separate, much more fanciful continuity. It was definitely a "kid-oriented" show and had some offputting qualities -- and it was strongly anime-influenced in some ways -- but sometimes it could be pretty damn impressive and moving in between the silliness. As for
Static Shock, I disagree that it was "childish." It was a bit younger-skewing and lighter in tone than the rest of the DCAU, but at least its first couple of seasons were often pretty smart and interesting, although it eventually moved away from the more character-oriented, street-level storytelling in favor of constant superhero crossovers, celebrity guest appearances, and gimmicks.
Green Lantern: The Animated Series is also pretty good; it suffers from the limitations of 3D computer animation on a TV budget, but its writing is strong and smart.
Of the current Marvel animated series on the air, the only one that really stands out is
The Avengers: Earth's Mightiest Heroes. But if you go back a couple of years,
The Spectacular Spider-Man was a really well-written and well-made show, though I didn't care for the character designs. It was from Greg Weisman, who also made the classic
Gargoyles and now runs the excellent
Young Justice.
And
Avatar and
Korra are simply the cream of the crop -- not technically superheroes, but the best thing in TV animation in decades, and one of the best things on TV
period. And yes, that's even with being rather "kid-oriented," especially the first series.
