My 9-year old daughter and all her friends are crazy over Mamma Mia, they keep watching it again and again and sing all those great ABBA songs. The plot is built around the gold Abba songs (which the *actors* sing), with a mother and daughter living on a sunny island, and daughter about to get married looks for her unknown father to be at her wedding. Eventually, 3 show up and the mother (Meryl Streep) gets her romantic moments too. Pierce Brosnan sings horribly, but that doesn't spoil it. It's fun and innocent, but also has a lot of strong sexual hints, needs guidance.
