It would be a very sad movie if they tried to be honest. From everything I've seen and read, the guy had the mind of a child. I don't mean he was disabled or stupid, he was just very naive and didn't have a full grasp of what most people call normal life.

And if they didn't make it honestly it would just be a generic musician biopic and people would absolutely hate it. Maybe after more time has passed they could approach it realistically. A movie on all of the Jackson kids maybe.
