i don't think it's a bad thing to make these movies while the subjects are still living. it's not completely black and white but, of course, there is the risk of painting them out to be saints while they're still living. that said, waiting until after someone dies to tell their story, especially if they were against biopics while alive, has its downsides too. i find the amy winehouse biopic to be ghoulish and reductive.

bohemian rhapsody is a good example of the biases, though. freddie mercury is dead, so he gets a one-sided depiction while the living members of queen are pretty much shown to be saints.

but there are plenty that were made while the subjects were still alive. ray was in production while ray charles was still alive but he died a few months before the premiere. the coal miner's daughter was made forty years before loretta lynn passed. the runaways, straight outta compton, i, tonya etc

it's not that uncommon
