I have as yet to see a single 'docudrama' movie based on any rock star that was even remotely as compelling as just watching footage or listening to the music of the actual star.
That Def Leppard VH1 docudrama that came out in the 1990s was laughable. The flick concerned itself roughly with the years 1978 to 1988.
The Buddy Holly Story with Gary Busey was one of the better ones.
I'd just as soon see footage of the 1978 stadium shows Van Halen was opening up for/at the bottom of the bill of than watch a bunch of actors pretend to be Van Halen.
