It's always good to see one of Tennessee Williams's less frequently performed plays being revived on Broadway, something other than The Glass Menagerie or A Streetcar Named Desire. For that alone we should be grateful for the Roundabout Theatre Company's presentation of Williams's rare excursion into the realm of romantic comedy, The Rose Tattoo, opening tonight at the American Airlines Theatre. Under Trip Cullman's fearless direction, the production gloriously embraces every morsel of this sweet, funny, and, yes, quirky (because, really, it is still Tennessee Williams) play. . . .
