Eddie Murphy's latest latex comedy, Norbit, is an unusual mixture of abject stupidity and sheer genius. If you've seen the previews - and is there anyone left who hasn't? - you've pretty much gleaned the plot, which finds our nerdy, titular hero (Murphy) trapped in matrimonial hell with the punishing, frighteningly obese Rasputia (Murphy again), and yearning to win the heart of his one true love (Thandie Newton). From beginning to end, director Brian Robbins' movie is formulaic, repetitive, obvious, and not nearly as hysterical as it wants to be. It's also one of the few comedies of recent years to be touched with something approximating brilliance.
