Matt Slocum’s review published on Letterboxd:
Together with its predecessor, The Godfather Part II creates a truly unmatched film experience. Al Pacino tops his performance in Part I by showing us Michael Corleone dropping further and further into criminal life. It is both harrowing and heartbreaking to say the very least. Robert De Niro also contributes fantastically to the film with his role as a young version of Vito Corleone. We see Vito's rise to power from when he was a young boy immigrating to the United States all the way up to the births of his children.
Part I by itself was unfathomably good, and Part II in some ways makes it even better. It expands on the story and allows us to appreciate every little aspect of Part I. I said this in my review of Part I, it is probably the best film I have ever seen. While at this point I'm not prepared to say that Part II is better, together they create a film experience that is better than the sum of its parts. After seeing Part I I really didn't think that was possible, but it is.
