Part Two is deeper?
I think I've heard it all. The main story line is truly skin deep.
What was the main story line in part 1?
Vito trying to be assassinated? Saulatso being killed? Michael becoming a Don? Michael cleaning house? There was no central plot, it was just superstar actors putting on a show. I have nothing against Part 1, I probably watch Part 1 6/10 vs. Part 2 just because of Brando, Caan, along with Pacino.
At least Part 2 had a storyline from beginning to end.
I used to not like GF2, but after having watched it several times, I appreciate it much more. There's small bits and pieces that don't stand out that you appreciate after having watched it.
It had a weaker cast because no Brando,James Caan, Castellano, Vigoda. GF2 has more subtle stuff, more of a chess match you're watching.
Everyone was on the same page in GF1, the Corleone Family were the true protagonists.
Part 2 there's just more mafiaesque activity going on, Fredo was a traitor (even if it was unknowingly), the way they set up Senator Geary in that brothel, the way they brought in Pentangeli's brother when he was testifying in front of the Senate, the betrayal, the breaking down of the Corleone Family. Part 1, the only betrayal really is Tessio turning to Brazini after Michael becomes Don. Even that, and Carlo beating up Connie were dead obvious just awesomely executed.
And DeNiro's time as an up and coming guy in that time in New York was also very important. It's something I didn't care for initially, but I think it was well done to parallel Vito's rise and Michael's rise and the similarities. It also shows Don Tommasino and why Vito is so loyal to him and vice versa.
