I don't typically write reviews. I have seen a lot of animes but the negative reviews this one gets are from people that didn't really invest into the story and gave up after 3 or so episodes. As of episode 11, I am enjoying the anime and will say the story is a bit slow but that doesn't make it bad.
If you have free time and aren't afraid to try this anime then I would say go for it. Sure it isn't the best thing of the decade but most things won't be. Doesn't mean you can't still enjoy it for what it is.
