After four days and nights, season 1 and season 2 of PB was finished at last. Ignoring the ridiculousness of the drama, I get at least two things: 1.the importance of faith; 2.no permanent friends,no permanent enemies, only permanent intrests 

  Every one has a dream.Michael devotes himself to  free his brother; Sucre's biggest dream is just living with his girlfriend and unborn child; Even Bagwell has his dream----windup the Bagwell clan. Once I'm aware of this, a feeling of lose strikes me. They all have dreams and always stick to their faiths, but how about me? how about us? Even though some of us have dreams, how many will devote the whole life to make it true?Maybe this is just the biggest gap between American and Chinese

  In the drama, there are only three people are completely reliable to Michael----Sucre, Sara and Lincon. As for other men, they are willing to kill each other when their intrests are at variance and can also become temporal friends when they have common interests. Maybe everyone just live for their own interests no mater he is Chinese ,American or  European.  Greedy is in born with man..
