This really is not a serious movie. But then, who could possibly have expected it to be. Three lively and exceptionally attractive young actresses duck and dive and dance and fight in a film that is visually witty and its stars displaying admirable verve. The sheer silly grinning delight of Cameron Diaz is noteworthy. "Charlie's Angels" makes no demands and delivers what it promises. In short, it is significant only in pleasing. And that is enough.
