And you think YOUR family puts on the pressure. Michael Corleone hardens into a ruthless, cold-eyed villain, while in flashback we see his youthful immigrant father take the first steps along that fateful path. The "contemporary" scenes sometimes drag, but the flashbacks to Italy, and immigrant New York in the '20s are brilliant. The final scene is one of the most heartbreaking and tragic moments ever filmed.
This is an amazing film, but it is rife with the dangers of materialism. All of the killings are "justified" by business decisions, the optimization of profit, getting a bigger slice of the pie, etc. Really shows you how dangerous money can be.
