I really enjoyed this show. It's not a must see but if you can watch it you should. I think it's on Crunchyroll.

I guess my problem is that it's a short show. The good thing about that is that it's not going to overstay it's welcome. But there's side plots and there wasn't enough time put into them to make me care. It came out in 2015 and I think that's recent enough for me to not spoil the plot. If someone wants to talk about this I'll use spoiler boxes.
