The show always looked appealing, but all the teasers were released, I lost track of the actual show, and haven't found the willpower to actually watch it all.
It's actually really beautiful. The story is well-written and the art style is downright amazing! And if you're willing to deal with a lot of cliff-hangers and some clunky animation (in the first few episodes especially) it's worth it. It's already finished season 1 so if you've got a couple hours to spend I would recommend it!
Besides, if you watch the show you get to meet this guy!
