I am not sure it will be "one final time" for Michael Mania. I used to think that the thing wouldn't keep on going, but we're getting a completely unexplained resurgence right now - obviously TikTok is a factor but WHY is it resonating so much there all of a sudden?
The movie is definitely going to put the albums on the charts and have people talking Michael Jackson - for better or for worse. Then after that there's potential for posthumous single releases, documentaries, concert video releases, poetry, drawings, diary musings, interviews. I don't think Michael Mania needs to have a "one final time". I think there is plenty in unreleased music, footage, concerts, insights, documentaries, memorabilia, and everything else to keep this thing going for decades yet.
Thriller 50, Thriller 60, Thriller 70, Thriller 80, Thriller 90, Thriller 100...
For as long as there are artists inspired by Michael and sampling his music there's going to be some sort of public interest in Michael Jackson. It's kind of like the Michael Jordan legacy - many of those who buy his shoes have never seen him play, but his name is synonymous with excellence. At worst, Michael Jackson will always be a matter of curiosity and his contribution is so deeply rooted in popular music that he like the Beethoven on pop, in 100 years people are going to search out the progenitor sounds and styles that influenced the music industry and Thriller, his music videos and his legacy will loom large.
