Can you give us a reactionary perspective on Puella Magi Madoka Magica?

I'm not sure it needs a reactionary perspective. Not everything needs to be political. That said...
This series does for the Japanese concept of the superhero (which is what magical girls are) what Watchmen did for the western concept of the superhero – and does it every bit as devastatingly effectively. And, as with Watchmen, nothing in the genre will or can ever be the same after this.
Certainly, if I had a daughter, I'd show it to her. It has some very important messages for adolescent girls – be careful what you commit to; consider consequences; don’t throw away tomorrow for temporary happiness today; don’t trust appearances; don’t believe words just because they come out of a pretty face (or a cute cat-being); find out exactly what’s in a contract before you sign it; if something sounds too good to be true, it probably is; don’t assume that everyone else has the same sense of morality that you do; there’s such a thing as being too nice to others; some wishes don’t come true, and often it’s better that they didn’t.
