The great guy like that cannot be existed in reality society, I cannot agree with you more on that point! ,Yeah, It is impossible! But the moive is focue on what the author want to tell. Just like I wanna to improve my english , I am half crazy to watch moives and teleplaies whether it is good or bad ,deep or simple , Americal or British,literary even pornographic.

　　so ,now can you show me what the author wants to tell ? "Think" , think the father ,the girl ,the guy ,ant till the society.if you put youself in their position what you will do. and what the things will be. and we will have different answers by ourselves. That's just my appreciation.
