I have not been able to watch The Godfather in recent years. The first scene — the undertaker asking for "justice" — is too overwhelming and I can’t go on.

Those of us who are students of the cinema may want to compare Coronet techniques with the films Bunuel made in Mexico. Those of us who are not students of the cinema may want to just watch as many of these movies as we can safely handle. Here is the link:
