This is by far the best movie of the year. (Mind you, I am also a HUGE MJ fan, so I'm well aware of my bias.) Ortega did a great job with the documentary; arrangement of the numbers and the weaving of the other people (dancers, musicians) into the rehearsal footage was very well done, as was the scene selection for new video (for Thriller, Smooth Criminal) to go with the rehearsal footage.
Of course MJ was flawless; he still had his voice (and he sang most of the stuff; Smooth Criminal was mostly lip-synced) and his moves. He was such an adorable person, and it's quite sad the world won't be able to experience that immense talent and kind soul again. Highly recommended for every MJ fan.
