The reason this part is inferior to its predecessors is that Coppola and Pacino have contaminated the character of Michael Corleone. His stoic, remorseless attitude and his laconic presense were completely degenerated in order to push the plot about his redemption. Nobody likes to see Don Corleone becoming a pussy. On a side note, miss Coppola puts on an abysmal performance and Garcia, who is quite good as a gangster, can't just pull off a serious Godfather.

The end of the saga is much weaker that the previous two chapters. May be it's because it's shown under different light. The movie is more concerned about political intrigues that a inner mafia life. Al Pacino is so weak that you are feeling a bitter taste all the time. Still it's the part of one of the greatest trilogies ever made.
