No way no to two. 2 may be better than 1. At least the equivalent.
I agree with you. Part II was every bit the equal of I.
The first time I saw Part III, it was just awful. A couple of years later I saw it again and it still is not very good but not quite as bad as it seemed at first.
I bet “The Godfather” has more lines which are regularly quoted than just about any movie ever.
