I am cautiously optimistic. I did come up on anime and manga. That Masahiko Otsuka will be making this his final work (although we've heard that sort of thing before) is really intriguing.
I'm not expecting to be STAR WARS, but star wars. This is the sort of sandboxing that can be enjoyable (unlike, say, major canon pieces...).
These things are often hit or miss. I believe there are 9 episodes intended: I would expect 3 of them to be worth watching, 3 to be pretty fine to have on in the background, and 3 to be utterly skippable.
