Intro: Madoka Magica is my personal Favorite, but my reviews are unbiased (i try) so i shall talk about the pros and cons. (it just connected with me personally) .Yet, there are flaws that may affect some people.
Story:10/10, Ok not many people argue against that Madoka has an amazing story. With so many twist and turns your left mind blown, and with a roller coaster of feels. Thus a 10 out of 10 (wont spoil anything)
Art: 9/10 would be 10 out of ten, but somethings are not rendered smoothly and thus sometimes the charters don't look like they belong there(only noticeable after many re watches 1st 3 times blinded by story).
Sound: 9/10 Generally Great, many amazing songs, yet i personally thought the op should have changed in latter episodes(you shall see why). Yet, the ost's are amazing. They fit right in the moment. They are dark when its called for, epic when things get real, and just plain beautiful when the feels hit. Thus due to the op not changing to fit the story a 9/10.
Characters: 8/10 The weakest link in Madoka. The characters personalities are stereotypical and Madoka is a winy you know what, for about 90% of the series. Yet, over their stereo typical personalities the characters do change. They become insanely human as the story progresses. Its not the personalities that's the good part of the Characters. Its what that person morally represents that is good. Yet, the lack of good base personality results in an 8/10
Enjoyment: 10/10 (results may very upon tastes) Madoka Magica isn't for everyone. it is a serious emotional tale. it is a good watch for most, but is only truly amazing to some. thus results may vary.
Final:9/10 Madoka magica is a wonderful tale. with amazing music and plot twists that a sure to satisfy all, but only truly amazing to some.
