Random thoughts:
— Since I'm the kind of viewer that doesn't really care about plotholes and can tolerate a sizable amount of oversold drama, maybe this show is a good fit for me
— On the other hand, I don't care at all about any of the characters yet, so maybe that will become a problem if it doesn't change later on. In that respect, this show was the opposite of Mouretsu Pirates. Mouretsu spent its time doing character development and setting explanation, and Symphogear spent its time creating spectacle and oversold drama without bothering with much characterization or making its setting make sense. Thankfully, neither of them drowned in fanservice.
— I can definitely see how that scene in the end of Symphogear Ep1 was inspired by Madoka. Specifically, some of the Sayaka scenes.
— If this show goes "DEEP", so to speak, with the music vs. noise symbolsim, I'll laugh at it and be incredibly entertained.
— The insert song duet and concert scene were pretty awesome.
