Did she do anything wrong comrades? She sacrificed her humanity to stop the collectors and stopped the laws of cycles for turning magical girls into witches. Foiling the plans of extraterrestrial beings that only wanted entropy.
1 post omitted.The Rebellion movie of the Madoka Magica series was arguably worthy to be called "based" in similar way to how movies like and ''Gone With the Wind", not to mention perhaps even several cowboy movies, could be considered to have progressive or revolutionary themes, despite that some of them might have reactionary sorts of aesthetics or nostalgia at multiple parts.
Qualitatively Akemi Homura, at the conclusion of that movie, was able to give, through her actions, to her fellow magical girls both the opportunity to have the normal life that had been taken away from them and the continued existence as magical girls who initially were to have been cast into unhappy, miserable existence, because their aforementioned "normal lives" were the cost paid, as result of their acquisition of power (feminists and communists can surely find some positive messages there) and thus invent in the "immanent reality" the better future that is not always the unreachable ideal and that is redemption and salvation that are made truly achievable. Of course in the context of the Madoka-verse the problem of the Incubators' goal to maintain the universe is still unsolved partially, so that is one of the major background contradictions likely that must be reconciled.
