I agree that GF2 is, without a doubt, the most complex of the films. There are so many scenes that require rewatching, not just because you love them, but because you almost NEED to watch them.

For example, there are so many ways that you can interpret the scenes when Frank is testifying. Why does he decide not to? Is Michael holding his brother hostage? Or is it really between the brothers?

What about right afterwards, when Michael and Kay have their famous fight? What is Kay implying about Anthony? My brother always thought that she was implying that Anthony inherited Uncle Fredo's brains (this was before GF3), but then there is the remark that Michael makes to his father in GF, that Anhony can read at 3 years old.

And of course, we haven't even touched on the whole Fredo issue.

Although GF3 has its own complexities, they are a more of a muddle than something that makes you want to think.
