Every time the late singer's image popped on-screen during the show's Las Vegas premiere on Saturday night, whether as a tyke with a golden voice as part of the Jackson 5 or as a Thriller with a sequined glove and a miraculous body for dance, the sold-out venue erupted, if only for a snapshot moment. But clips of Jackson being MJ, however magnetic, can't sustain an hour-and-a-half show dedicated to his music, nor can a dancing Bubbles the chimpanzee, big-Afroed J5 impersonators, a baffling mid-show cello solo, a sexy contortionist act atop a children's book, groups of synchronized mummies in hoop skirts and, most curiously, a life-sized dancing glove that looked more like a half-dead starfish.
