21 is a movie about game, money and greed and also about how someone can lose his self control when it's all about making "easy money"Â… In the materialistic world we live nowadays money is the center of many things, even those which were supposed to have nothing to do with it, like love or friendship; so making "easy money" is a real temptation even if you have to lie, forget your old friends or to do schemes to achieve it! The main character of this movie can tell it very wellÂ…It's a nice movie about this subject and it shows us the frightening world of Las Vegas casinos'. The plot is quite interesting and appealing and the cast is also good. I score it 7/10.
