On-screen, "Bad 25" moves in the style of a great pop song.

The posthumous campaign to polish Michael Jackson's tarnished reputation continues apace with this Spike Lee infomercial, commissioned by Sony and the money-grubbing Jackson estate to promote the 25th anniversary of his 1987 album "Bad.''

Though at times a tad worshipful, the film's tone is ultimately more awed than hagiographic, its commenters too cleareyed and candid to back away from negative publicity or public disenchantment.

A tribute to the master craftsman and musical talent that was Jackson and not a penetrative investigation of the man who made the music.
