The Godfather was so masterful that it was impossible to overcome him with another work. Of course, The Godfather: Part II is also a masterpiece. The story beautifully follows up on the previous part and explains the backstory of the godfather himself, more precisely Vito using flashbacks. It's unbelievable how much Godfather: Part II did and it's damn hard to choose which part was better, it's more a personal preference. Personally, I'm leaning a little towards number one, but it really doesn't mean that the second part is worse. It is as masterful as the previous one and overall it is a MASTERPIECE and MUST-SEE film.
