As I don't actually use reviews when decided whether or not to watch or read something, my reviews probably aren't that helpful, I just use them to say what I like and what I didn't like.
Sorry :/
Honestly, I started watching this anime because it was on my to watch list and it looked good, that's all there is to it.
After the first episode, I was hooked, sometimes it takes me a lot longer to decided but with this I knew straight away I would love it.
And I did, I really like anime with magic and that fantasy element so this one was up my alley.
I liked the characters as well, well I was a wit weary of the characters to start of with, but they grew on me.
I had a feeling that the big thing that happened (no spoilers) would because I tend to be good at reading those sorts of plot twists but still, I was shocked.
I did not expect (SPOILERS) Natsume to die though, this shocked me so much and yes, it made me cry too.
I guess what I didn't like was, as with most things, that there was not a lot of back story. Granted there was a lot more back story than some anime I have watched but I still felt like it was lacking a little.
The ending, while it was good, ended very suddenly and was rather cliff hangery. To be honest it left a little room for a sequel but more often than not, a lot of them do and we never get one so I'm not holding any hopes just yet.
I guess another dislike I had is, well it did fell like it was something I'd seen before, it lacked a little originality and while I did enjoy it, it was rather similar to other anime in the same genre.
I did enjoy the anime but there were times I did consider dropping it, not so much because I didn't like it but because there were quite a few main arcs (if you can call them that) and I felt it dragged on little.
Saying this, It did work well as a 24 episode anime and I do not think it would have done so well being any shorter.
So this review is probably not helpful but thats not really why I write them so... Sorry
