Despite my rating in MAL, this anime will not be for everybody. It's fairly niche show despite the recognition the internet has given to it.
The visuals are very good and creative with lots of gags in these. Bocchi is pretty much why you will sign up for the show and maybe the music. This is where it kind of falls apart. If you don't like her, you're not going to enjoy it as much. Well, are the other characters are as developed as her? No. The other 3 aren't as good as it could be. I think the first character of the band you meet is in my opinion, the least used character. They didn't give her as much time as the other two or maybe I'm missing something. The music is actually good. This is critical for a show about music though I prefer classical piano pieces. Don't take my word for it because that's just my own taste in music.
Don't get me wrong Cloverworks did an incredible job in this adaptation. This is how you should do adaptations. Maybe not this exact way but you get the idea. It worked very well on the audiences it was targeting but outside of it, your enjoyment will vary. Even more so than usual.
