Jakub Flasz’s review published on Letterboxd:
I think I understand the idea of symmetry that Coppola introduced in "The Godfather Part II", which was then carried through into the final part as well, thus bringing all three films together and cementing the idea of them being a bona fide trilogy. Though, I can't help but feel that in terms of the rhythm of the story, this film feels at least a bit repetitive. And that would be my only nitpick.
Other than that, "The Godfather Part II" is an example of masterful storytelling, where nothing gets rushed or brushed over and the characters have the time and space to grow and fulfil their arcs. Then again, with so many master class actors and a story so tight and engrossing, how could anything possibly go wrong? I truly love the idea of setting this entire story within vague constraints of historical facts, like the Cuban revolution, or (in the third one) the papal succession, which adds immensely to the realism. I love how the actors would speak Italian and expect the audience to either understand it or read the subtitles, which nowadays would be rather frowned upon. And finally, I can't even find words for how much I adore the way this whole story is written; how the characters are multifaceted, layered, complex and subtle and how their arcs are rooted in gritty realism.
In the end, the true testament to how good those films are is the fact that having just watched them and having seen Michael Corleone grow into an anti-hero, I have this subconscious feeling of sympathy and adoration to a cold-blooded murderer. And truthfully, "The Godfather" together with its sequel make the notion of becoming a gangster seem enticing.
