My neighbors' son just got his A+ on his paper on GBU, and I had to send you his ideas. Im paraphrasing because I dont have the paper in front of me, but I had to share this with everyone. Comment if you like but please read..the kid is genius.
"The Good and the Bad, in this movie, represent the opposite ideals of man. Either what we aspire to be, or what we fear the most. THE UGLY, Tuco's character, is not in fact ugly, but IS, the representation of man. Man with nothing to hide behind, his raw nature. Greedy, opportunistic and completely along for the ride with no idea how to get to his destination without taking from others.
Tuco is weak, uncomfortable getting too close to either of the polar representations, but he sticks with the representation of the good because he feels he can easiest manipulate him. Tuco's character is like most people feel, uncomfortable, clumsy, uncommited to anything specific.
Tuco likes to see himself as "The Bad", like many tough guys do. But when faced with the awe of what pure, uncomprimising evil looks like, he cowers and seeks to escape. He finds it much easier, even if never believed by THE GOOD, to represent himself in the middle.
In the end, THE GOOD and THE BAD face off, and man's representation is stuck right in the middle of their conflict. Unarmed, and unprepared. His only grace is that neither force saw him as a real threat to begin with, only as THEIR tool to their means."
Say what you will...some kids are doing their homework.
