the greatest scene in ALL of film history is the scene outside where Don Vito tells Micheal that he had hoped to one day see him "pull the strings" it shows that the Don did what he felt necessary to protect his family and to allow them to have a bright future and for the family to be respected. This scene actually changed my life. And then of course the baptism/murder scenes are great.

In 2 I like the scenes with Micheal in Pentangelli's home, Micheal with Tom after the bedroom shooting, and Tom at prison with Pentangelli, as well as Vito sitting with his children after the killing of Fanucci-great shot.

In 3 I like the Atlantic City attack and the "they pull me back in" scene.

There are so many great scenes in the trilogy I could go on and on.
