Following Michael Corleone (please read)

At the beginning of the movie The Godfather, I was given the impression that the movie was going to be focused on Vito Corleone but as the plot went on, the spotlight drifted off Vito and onto Michael's growth as a mafia family member. The reason I thought Copella focused less on Michael and more on Sonny, Tom Hagen and Vito was because the movie was about the mafia family 'drama' and because Michael had chosen not to be a part of it. Copella informed us of this at the very beginning when Michael told Kay Adams, at the wedding, "That's my family Kay, not me." After a number of unfortunate events that happen to the Corleone family, Michael is slowly drawn in to the family issues and pulls himself away from Kay. A very important part of Michael's development is at the hospital when he hides his father and tells him that he is with him and will be there for him. After that, Michael was increasingly involved with the mafia world until the point of no turning back. This was when he killed Sollazzo and McCluskey. Once this was done, it would never be possible for him to go back to being a normal member of society or get out of this way of life. This was illuminated by Copella by adding loud train noises as he was taking the gun and when he killed Sollazzo and McCluskey. Trains are only capable of going one way because their tracks follow a line and going backwards is very tricky and often impossible.
