In the spoof-crazy 1990s, it was a good idea to send-up the reigning queen of MTV, Madonna. Impeccably copying the look and style of 1991's "Madonna: Truth or Dare", star and co-creator Julie Brown was not only precise in her satirical prodding, she was quite timely as well. This Showtime production runs just under an hour, with maniacal Brown not simply singing and dancing à la Maddy, but lampooning the video vamp to the nth degree. The original songs--take-offs on Madonna's proved hits--are bits of pop-genius in their own right, and Brown sells this catty, nasty, silly special with unabashed vigor. The alternating black-and-white and color photography gets the look of "Truth or Dare" down pat, while our new heroine, Medusa, battles with her ass-kissing staff until she gets her way on everything. Some ideas don't come to fruition, and many are simply run into the ground without benefit of nimble handling. Still, Brown is so compulsively watchable (and likable), she kicks this thing into campy high gear with her unstoppable energy and unflagging chutzpah.
