yeah I have. I think they suck.
That does not matter what you think about it. The point is that they have an audience who pays to watch them perform. Same with Broadway plays about music acts (Tupac, Cher, Tina Turner, Motown, Michael Jackson, Frankie Valli & The Four Seasons, etc.). From what I understand, Broadway tickets are not cheap. Although not about a music act, the Broadway musical
Hamilton, about one of the United States "founding fathers" Alexander Hamilton, was a huge hit and was even filmed and shown on Disney+. On PBS, they've shown concerts by Beatles & Pink Floyd tribute bands during pledge week. I've watched them & both had a large audience, hundreds maybe even over a thousand people in the audience. Look at all these Elvis impersonators, in Las Vegas some are even ordained to marry people. The same way lots of people are into tribute acts, many also watch biopics, whether they for movie theaters or made for TV. The Osmonds have 2 different TV biopics, in one of them Marie plays their own mother. Even lesser known acts like Bobby DeBarge & Michel'le have biopics. There's also one about John Lennon as a teenager called
Nowhere Boy.
Do you really think all of these biopics would be made if there was nobody watching them? More people watch biopics than filmed concerts. That's why very few concert films have been made and released to movie theaters, they generally don't make make much money. Filmed concerts are more likely to be shown on TV or just straight to home video. You keep crying about
Bad tour DVDs, when Mike never released any of that stuff when he was alive, only the
Dangerous concert. If Mike was alive now, it's still unlikely he would do that. I don't think that
This Is It movie would exist either. So no different from the estate you complain about.
