I plan to watch these:
Big Hero Six: The Series
My Little Pony: Friendship is Magic
Disenchantment
Dreamworks' Dragons
The Adventures of Puss in Boots
All Hail King Julian
Kung-Fu Panda: Legends of Awesomeness
Voltron: Legendary Defender
Big Hero 6 is reasonably entertaining, though not as good as the movie. Its main asset is that it reunites most of the movie cast, save only Damon Wayans Jr. and T.J. Miller. But Khary Payton is better in the role than Wayans was, if you ask me, and given the recent revelations about Miller, maybe the show's better off without him. (And Stan Lee reprises his movie character on a recurring basis. He'd already recorded his role for the full second season before he passed away, so he'll be back next year.) It's in 2D cel-styled animation rather than 3D, and I'm a bit disappointed that it doesn't use the same striking 2D character designs used in the movie's end titles.
Disenchantment is mixed. Well-made, but not nearly as good as
Futurama. Being on Netflix lets it go darker and more extreme, but I don't think that makes it funnier. It does take a pretty poignant twist in the final couple of episodes, though.
Dreamworks Dragons is excellent. It's another show that reuses the majority of the movie cast (ironically, T.J. Miller
does reprise his role on this one), and it does a good job retroactively filling in the continuity between the first two movies, so that it feels like an integral piece of the whole. It can't really evolve the main characters much beyond bridging the movies, but it adds supporting characters and antagonists who have rich character arcs, with some excellent guest performances by actors like Mae Whitman, David Faustino, Mark Hamill, and Alfred Molina. The animation looks gorgeous in a lot of ways, but is sometimes subject to budget limitations, in that it rarely features large crowd scenes and tends to rely too much on a single digital character model for its secondary villains, so that nearly all the "dragon hunters" look like clones with different armor and hairstyles.
KFP: Legends of Awesomeness is from the same studio, but not quite as good. It can be entertaining and funny, but it doesn't fit the movie continuity as well. It has very little of the movie cast -- only James Hong and Lucy Liu return -- but Mick Wingert does such a good Jack Black impression that I can hardly tell the difference.
Voltron looks great; it's from many of the same creators as
Avatar/Korra with a similar design style. And it has pretty good character writing. But the storytelling doesn't always hold together that well. It also isn't great at recapping past events and kind of assumes that viewers remember returning characters and past plot points, so it's a show you're better off binge-watching all at once now that it's finished.
The new
She-Ra on Netflix is pretty good, and
The Dragon Prince (also from
Avatar/Korra veterans) is fairly interesting.
The other Tales of Arcadia show '3Below' is probably worth a look aswell.
It has its merits (Tatiana Maslany!), but I found it flawed. The Varvatos Vex character (the warrior-protector of the two teenage leads) is deeply annoying and unpleasant, in both personality and performance. The first season takes place simultaneously with the final season of
Trollhunters, and there are cross-references between the two, but the fit is imperfect and it leads to some awkward storytelling. Some parts in
3Below would make no sense at all if you hadn't already seen
Trollhunters (but I guess the advantage of them being Netflix shows is that if you get one, you automatically get the other), but the parts that appear in both aren't told in a perfectly consistent way between the two.
