Review of Sing "Yesterday" for Me

This is the first anime I've watched that I can consider to be tearjerker bait. I say this because it had the makings of being a great show, with a good OST and somewhat unique art style but the show itself is just so mediocre with a hollow story. I've seen worse shows than this but at least they brought something new to the table. I kept waiting for the story to develop into something better since I thought it was 18 episodes but to my surprise there's actually only 12 and I would say it was a huge waste of time. Barely anything of importancehappens except poor character and relationship development. It also didn't help that the ending felt rushed. This is my first review on here and I had to write one because this show was such a drag and so pointless that it made me a little mad. Go watch a better anime and don't bother with this one.
