There isn't much to say about The Book of Mormon that hasn't already been said. The musical, from the brains behind South Park and Avenue Q, is about two silly missionaries in Africa and has already won nine Tony Awards, including the coveted best musical category. When it played in Boston, it was "the hottest ticket in town," according to The Boston Globe. When it opened in London, it broke single-day sales records. SF Weekly's own reviewer said the show managed to "transcend simple mockery, elevating absurdity to the point where it comes back around to earnestness." That's pretty hefty praise, but a year later, The Book of Mormon is living up to the hype. It's touring all over the U.S. and selling out theaters from Orlando to Portland. A nine-week San Francisco run begins tonight. Get tickets early — last year a lottery had to be introduced.
