"One+One." The part where the Rolling Stones are recording "Sympathy for the Devil."Which is the half great film?
And the earlier Fellini (except Amarcord). I guess the cut-off point might be Juliet of the Spirits? Except for Amarcord and maybe Roma, that may be the last undoubtedly great thing he did. His later stuff kind of dissolves into episodic fantasias like Satyricon (or somewhat tiresome pop culture indictments like Ginger and Fred), but unlike Juliet they increasingly have less-and-less holding them together except for the spectacle.
