There are a few key things in Bocchi's favor, other than its high production value, unique, experimental animation style, and anomalous lack of sex perverts on the production team: honest writing and actually being funny. Bocchi the Rock! knows it is a band anime as much as it is about the band's members. This is a show about improving at your craft, and improving at that craft with others. It involves the highs and lows of laboring for your passion. It has been said that this show accurately portrays the social dynamic of a rock band - to that the reviewer cannot speak, but is not surprised.
You learn to know the characters not just as a collection of shallow tropes bouncing the usual slice gags off each other, but as real (enough) people who subvert their apparent archetypes and grow with one another. And the show doesn't settle for "character transformation" in the most boring and obvious way, like Allison's notorious goth-to-prep makeover in The Breakfast Club. No "ugly ducklings". You will find in Bocchi the Rock! surprisingly deep and likeable characters who betray your expectations of the same old, and they develop in a very natural way.
And it's pretty honest-to-god funny. It shouldn't be surprising when you can't predict a joke's punchline from the setup, but this is the state of anime in 2023. The jokes land. It's comedy. Above all else, at the time of writing, Bocchi the Rock! is worth watching for that alone.
