From the same animation studio behind Avatar/Legend of Korra/Voltron...

Now up on Netflix.
Fun game to play while watching it, "spot the Lego". There are Lego pieces used as parts of the background, some obvious, some not so obvious.
As for the show, it's OK, the animation doesn't seem as good as Avatar/Korra/Voltron (I also don't think Voltron is as good as Avatar or Korra), and it is written for a very young audience. It's basically one long episode, each episode picking up with where the last ended.
If you are bored give it a shot, it's not something I'll watch more than once.
