One problem I see is that a lot of biographies are pretty good at describing the person's life as far as social relations go but they usually don’t have only very shallow information about the actual topics that made the person famous. When I read the Steve Jobs biography I would have like to hear more about how he thought about technology and how product decisions were made vs his relationship to his daughter and so on. Same for scientists. Not sure how to do better but I think there is a risk that professional biographers describe only certain easily accessible facets of the person and not go into the depth of their work.
