This film is my favorite one from this great trilogy, it's simply a masterpiece. I have never watched anything well-written and perfectly directing like this in my entire life. I re-watched it many times, and every time I discover a new brilliant details. The way that Michael Corleone had changed, and how we saw the development and change of his character was the most amazing part. My favorite scene was when Michael said "I know it was you, Fredo, you broke my heart." Everyone must watch it.
