I'm not a pro on how to rate an anime but I will give my thoughts without spoilers. Some scenes don't make sense and are explained later without any credible logic, but I guess they had to keep the audience satisfied with what they wanted to watch. Some powerups come out of nowhere or the logic of why something is happening isn't right.
I did like the music though, good thing they used the original series' OSTs, and the opening isn't bad.
I liked Sesshomaru's, Moroha's and Setsuna's character development. It's very entertaining but don't try to understand the why to everything or look deeprly into it because as I said before some things don't make sense, which means you're not gonna enjoy the show thinking how something like that could happen.
(spoiler) I think it's nice they "brought back" Kikyo, I'm sure a lot of fans me included liked to see her again. My only question would be, why didn't the tree of ages (idk how it's called in english) didn't have a "personality" before? Looks like they took thsi out of nowhere and suddenly the tree can speak when it never did before during the original series.
