How many beach houses does Kevin Spacey need for God's sake? An inspirational teacher sets his class the task of doing something to make the world a better place, one of his pupils thinks up the idea of rather than paying back a good deed you pay it forward, thereby creating a chain of positive events. Under certain situations I can be justifiably accused of cynicism, but this really is mawkish, sentimental, manipulative dribble. A fine cast sharing a dubious career move.
