I tend to agree with appleonya. There are so many great scenes, that they weave a tapestry. It is the entire movies (1 & 2). I'm not real crazy about 3. I guess if I had to pick one, I guess it would be where Michael revenges his father's shooting by murdering Solozzo & McClusky. The tension building, restaurant noises, street cars going by, Michael's blood pounding, the actual killings followed by that music. Fantastic.

But if Clemenza can figure a way to have a weapon planted there for me then I'll kill 'em both.
