That's not how I see it, personally. To me, the biopic is a great opportunity to get the general public's interest in Michael peeked to the point that other companies will see a positive reason to invest further in him. I see the biopic as the beginning in some sense. After the biopic I would love to see more documentaries about specific times in his life, theatrical releases of concerts, more music released, more positive books, memorabilia everywhere, etc.
Basically, I want Michael to have what The Beatles have. Just all around, general acceptance of him as the legendary artist he is.
