Way too much of the film portrays nothing much more than two irksome punks in their pranking glory; but as it plods to a head, it is revealed that one of them is a loathsome sociopath leading the way to tragedy. Excellent acting, especially by James Caan as the crotchety old man with a bitter edge whose character develops powerfully. This movie insightfully examines weighty subjects including human depravity, broken family, peer influence among youth, terminal illness, lost love and loneliness among the aged, and of course ethics and justice (not in the horror genre). This is not an uplifting story, and the ending is somewhat disturbing, leaving a lot to be thought about.
