Thank you Lou and you are not wrong
For clarity, I thought I had missed something, being always hungry for and getting a kick out anything Godfather except Puzo droning on and on about Lucy, Fontane and Genco

As regards the story lines, from what I remember,
1. Luca Brasi's how evil he was and why he was so loyal to Vito
2. paedophile Woltz

this kind of makes my point about how Vito is seen through rose-colored glasses
1. as long as Luca was killing for him, his baby can be thrown into a fiery furnace while still alive
2. as long as Woltz gave the movie part to his Godson, he can keep molesting children

Neri's how brutal he was and why he was so loyal to Michael
