Tough question, because of the many Impactful Scenes. One that I feel is most important is the hospital scene when Mike goes to visit his father, and finds all the guards gone.
LOL. All the guards, and all the patients, too. That hospital was right out of
Halloween II.
Most impactful scene: my favorite is when Michael deals with Carlo.
After the baptism, they're all exiting the church. Rocco appears and whispers something into Michael's ear. Michael then stares ahead at nothing for a second, then just his eyes shift over to Carlo.
FFW to the scene when Michael and his entourage enter Carlo's home, and Michael walks towards the camera and says, "You have to answer for Santino, Carlo."
