It was a bad anime but a good experience. The studio put in a lot of love even if their techniques were lacking. While I don't consider it a good quality anime, I still love Alter Memory. And the soundtrack is one of the things they absolutely perfected.
R4KID Where's the problem ? One can like one aspect out of a thing whilst not adoring the rest. Acknowledging the music quality, but calling it "shit" because the production where it comes from is called "shit" would just be hypocritical. I do also have bad opinions on Senran Kagura, but that doesn't prevent me from saying the OST is marvelous (especially the themes of Yagyu, Ryona and Kagura)
I do think the anime was really shitty. The animation was super unbalanced, very ugly at a lot of times, and overall not really good quality. The story wasn't really brought to the audience as well in my opinion.
