Sometimes you just want to watch something trashy.
This anime is on the same level of stupidly, obsessively, melodramatic as Ano Hana. Take one main character with no spine or emotional stability, give them an emotional crutch for a friend, and then take it away! Sit back and watch as this child grows up increasingly maladjusted and in serous need of therapy!
But hey, I finished it.
I give one point to the anime because it's not grossly m I e, but then I have to go and take it back again because the art just isn't that great. Don't even get me started on the MMD level of cg animate for the concert scenes, and you have one mediocre anime. At least AnoHana was pretty too look at.
