looks generic as hell like damn near every music biopic. There's too many moving parts if you want to make a unique music biopic: you need actors that look like & can copy the energy/personality of a legendary musician, and you need a writer that knows about the era they are writing about and the artist themselves and their life story who can put all that into a cohesive 2 hour film. Not to mention the singing/performing, cinematography, editing, costuming and set design. Also these artists often knew other legendary artists, actors, athletes, etc and you have to cast actors to play them properly too, even cameo roles.
That's why documentaries and concert films almost always work better for these kinds of stories.
