My view is that they did intend to have a documentary or tour footage, to sell after the tour. Why not, it would produce lots of money as the fans out number the tickets.
Merchandising is big business. I think that makes sound commerical sense. MJ did alot of DVD's.
Also to have a teaser for the Thriller film, do think that would have been really great. I would have gone to that for sure.
I really talented person.
The This is it song, don't know. Love his voice, but when i heard the song i thought it was dated and then found out it was 18 years old or so. I think it was an add on. Someone dug it out and thought it was a good idea, for commerical reasons, I think it is not very contemporary and MJ i feel was very innovative
