Another reason to not like the book as a hardcore Godfather fan was that MW messed with the structure of the original novel and films. He spends too much time on the Corleone's enemies like Geraci. Puzo and FFC showed the Corleone's dealing with the threats they faced from enemies and dropped small hints at who was behind the plot like the Ola/Fredo phone call. But MW spends half the book on Geraci and other Corleone conspirators.
