The Boss must be so proud to have inspired such a beautiful film. It is a stunning achievement to explore so many powerful themes so well in less than 2 hours: teen angst, parenting, the immigrant experience, friendship, love, music, and more. Like others have said, this is one of the best feel-good movies. A lot of great young actors, good direction, great camerawork, costumes, it's all there, even if there are some anachronisms (modern world map on the wall, modern cars in the highway scene, etc.)
Remember, kids: Nobody wins unless everybody wins.
