One of the greatest movies ever. Which one do you prefer? Everything is perfect in these movies. The acting is AMAZING, the story is GREAT, the script is PERFECT, the drama is UNFORGETTABLE, the character development is BREATHTAKING (especially how Michael Corleone develops throughout the trilogy), the dialogue is WELL WRITTEN and the movies are both great. But I must go with The Godfather but Part II is not far away.
Easily the first. As a stand alone film it's brilliant. It's about the action. The second one slows down quite a bit and third is just rubbish.
