South Park mavericks Trey Parker and Matt Stone have made a fine art out of inappropriateness, but their hit musical, The Book of Mormon, is a much more nuanced satire than you might expect—and the songs are surprisingly good.

There’s a reason this show, cocreated with Avenue Q genius Robert Lopez, sold out its entire one-week run here last year. It tells the unlikely story of two mismatched Mormon missionaries who start to have serious questions about their faith after being sent to ring doorbells in Uganda.

Politically incorrect and outrageous? Pretty much. But it’s also pretty damn daring satire.

You get the chance to check it out again from Tuesday (August 23) to September 4 at the Queen Elizabeth Theatre.
