MICHAEL JACKSON'S THIS IS IT

For a film that seemed to have "commercial exploitation" written all over it, Michael Jackson's This Is It is an intensely loving and even indispensable piece of work -- a joyous celebration of performance drive, hard work, and a fearsome amount of skill. Culled from roughly 100 hours of rehearsal footage from the late star's planned concert tour, director Kenny Oretga's behind-the-scenes account doesn't offer much in the way of insight, nor is it meant to. Yet it's still a first-rate spectacle that, at times, provides an almost ridiculous amount of pleasure; somehow, miraculously, Ortega and his editors have shaped their footage into a documentary that boasts the kineticism, excitement, and boundless ebullience of a kick-ass movie musical.
