The story is imaginative and interesting- especially if you enjoy the Fantasy genre. However I really, really wish a native English speaker, or someone who reads/writes English as part of their regular job. 
The language makes the story difficult to follow in places and is very distracting, like the transition images that just say "In a few." A few what? moments? minutes? hours? 
I really enjoyed Season 1, and working my way through Season 3. It's like a dish where someone added the wrong spice, still delicious, just off and not as delicious as it could be.
