You had to have the Sonny/Carlo trashcan scene.
That led to Sonny leaving the house when he should not have.
Which was the ONLY way to get Sonny out of the house.
Without both scenes you would not have understood why The Godfather(Michael) had to settle the score with Carlo on the day of his son’s baptism.
If only Sonny Had an EZ-Pass, he would still be alive.
Sonny needed Yoda to teach him how to deal with his anger. But that was a different franchise.
