Really, these dancers and singers have gotten the gift of a lifetime. Because of Michael they have become household names overnight. They have been thrust into the limelight of the world and have received a huge jump start to their careers that no other entertainer could have provided. The dancers have two year contracts in the bag with AEG so they don't even have to worry about employment for now and in the future having Michael's name on their resume...well, that speaks for itself.
In the documentary, I thought they showed true appreciation for the opportunity to work with Michael. But the joy should be turned to sorrow now that their dreams of working with MJ are dashed before they even really began. Either what we saw in the movie was not real where their emotions are concerned or Michael is alive. That's the only conclusion I can come up with for the discrepancy. Otherwise wouldn't they'd have been more emotional the days and weeks surrounding June 25th?
