One of the recent Sundays, I watched the movie, Godfather. I first watched the second half on TV, and then the first half on DVD! Quite an amazing movie. I had read the book many years ago. It all comes so alive on the screen.
The defining scene which had even struck in memory even when I had read the book was when Michael Corleone takes on the challenge and kills the two people in the restaurant. In that one instant, his life changes completely.
I tried watching Godfather II, but gave up about a third of the way through the movie. It was getting way too complicated for me. Even with help from the Wikpedia page which tells the story in detail, I could not sustain interest in the movie.
