Review of Sing "Yesterday" for Me

Damn, this anime started off so well. I was in love with the sounds, the setting, the feeling. The voice actor for the main male MC was just phenomenal–it's the same one who voiced the wolf in Beastars. That voice is almost iconic now. For the first couple episodes, this anime was 10/10 all around. And then I'm just not sure what went wrong. Maybe it was the show trying to focus on the four main characters instead of the just the three in the first triangle? Maybe it was how even at the end, 2 of the 4 characters were just not redeemable in anyway? I guess it's just hard to like an anime when the characters in it are just not nice, for the lack of a better term. Disappointing.
