I think De Niro did an excellent job portraying Sonny. However, he was a little scary. He was going for more of a dangerous, phsyco Sonny. He did a very good job at it, but I think that Sonny was suppose to be more like a teddy bear-well a teddy bear that would kick the sh*t out of you, but still a teddy bear. James Caan definaetly did an excellent job in portraying Sonny, and De Niro would prove that he would portray a young Vito perfectly as well.
"I never wanted this for you. I work my whole life--I don't apologize--to take care of my family, and I refused to be a fool, dancing on the string held by all those bigshots. I don't apologize--that's my life--but I thought that, that when it was your time, that you would be the one to hold the string. Senator Corleone; Governor Corleone."
-Don Vito Corleone to his son, Michael
