The premise of this swinging Vegas picture is enough to carry it over its narrative rough spots. The unluckiest sap on the planet (William H. Macy) is employed as a "cooler" at a casino; his very presence can chill the hot streak of any patron on a roll. He's valued by the old-school manager of the place, a role given a two-fisted, bourbon-swilling incarnation by Alec Baldwin. Macy means to quit, but then he falls for a waitress (the excellent Maria Bello, from Permanent Midnight)--might his luck be changing? The subplots are pretty much a mess, but the frank sex scenes between Macy and Bello give the movie a truly offbeat feel. The tawdry air of a second-rate casino is also nicely done: This is not the new family-friendly Las Vegas, but a tough place of superstitions, sinister back rooms, and shabby motels. The characters are perfectly at home.
