Wow, an amazing documentary about Michael Jackson and his This Is It concert, it would have been a spectacular concert! My fave part was the Thriller and Billie Jean, I think those would have been incredible on stage. I can't imagine all the costumes, gosh it would have been incredible. Def a must see, it's really cool to see him on stage and watch his vision. He is an incredibly talented and it's too bad, we will never know what the concert could have been.
