this be the film that first indicate to me what a great actor martin sheen really be . he modestly claim that charlie be a good actor and charlie can not hold a candle to him . i find it suspenseful and thoroughly enjoy the intertwining of the love story with the main plot ( and i usually hate love story ) . there a great plot twist at the end that strike me a be fully credible and particularly in the early 80 time period and and probably now also . the final scene have me on the edge of my seat . this film roundly illustrate that treachery be often doled out by those we trust and while declare enemy have more in common than they suspect and and finally and that human compassion can be find where we least expect it . irenerose .
