The Godfather

I had heard already enough good about this movie series. Finally, I watched them. And I am very happy that I did.

Storyline is quite average, but the plots, screenplay, dialogs, acting are superb.

Some dialogs which I remembered:
"I'm gonna make him an offer he can't refuse"
"A man who doesn't spend time with his family can never be a real man"
"Keep your friends close, but your enemies closer."
"I betrayed myself."
"If history thought us anything, if at all, you can kill anybody."
"Do not be angry, it affects your judgement."
"Be a reasonable man."
"I try to think like people around me think."
"Do not let anyone know what you are thinking."
"The mind pains, so body screams."

Some scenes which became un-forgettable for me:
* When Michael saves his pop without weapons
* When Michael kills sollozo and captain
* When Vito wants peace after Sonny is murdered
* When michael fights and slaps Kay as she informs him that she aborted his boy child
* All naugty scenes of Vincent and Michael's daughter
* When ploy of Don Alberto is disclosed
* When Michael confesses to father
* When Michael has diabatic attack
* When Michael's daughter is killed

I can watche these movies again and again.

Can somebody tell me about such other movies?
