That would be a long list, I suspect, but as far as current shows, I'd say: Arrow, Nikita, Adventure Time, and...Star Wars: The Clone Wars, though that one's over now.
If we're talking in general: Batman: The Animated Series, Justice League, Justice League Unlimited, Batman: The Brave and the Bold, Battlestar Galactica, Star Trek (pick one, but I'm still working on DS9 and Voyager, TOS and TNG are my favorites), Smallville (at least when they weren't doing teen soap opera stuff), Ducktales, Chip N' Dale's Rescue Rangers, TaleSpin, Garfield and Friends, The Powerpuff Girls, and the list goes on. I couldn't remember all of them if I tried.
I do think Game of Thrones is interesting, but I've not gotten into the show much despite having read the books. Scandal seems interesting, too, but I've only seen a little of that and really like it. Marvel: Agents of SHIELD seems potentially good but I'm just not a Marvel guy, so...I'll get to it eventually.
