Blessed with a wondrously gifted comic cast and full of droll details, Mystery Men struggles in fits and spurts towards its climax. Transcendently witty in parts, it's also woefully sophomoric in others. Literally, this is the kind of movie in which someone gets off a brilliant line and then sits on a fork. Still, when this movie is rolling, it's gleefully on target, thanks primarily to the mordantly cocky Stiller and Janeane Garofalo as a latecomer to the superhero gang; her secret weapon is a bowling ball in which her dead father's head is encased. The comic chemistry between these two is fierce, and when you add the dryly funny Macy and the endearing Azaria (who finally gets a chance to let loose with his comic gifts), it's a hilarious joyride. Too bad that the gas tank is only half-full; this stunning cast deserves a first-rate vehicle. With Tom Waits as a weapons expert, Claire Forlani as the requisite babe, and Paul Reubens as the Spleen, the world's most flatulent superhero. --Mark Englehart
