Also, if Two Cathedrals is the best episode (which by far and away it is), any nominations for the worst? I'd go with The Long Goodbye, the one with CJ and her Dad. The West Wing doesn't seem to do CJ-centric episodes very well, Access (the 'documentary' about CJ) was rubbish as well.
It certainly wasn't the worst, but there's clearly a big shark being jumped over there. It would have made a great made-for-TV film, and the acting was top-notch, but it simply wasn't TWW. It's almost like they sat down and said: "OK, how do we get Alison Janney her Emmy this series?" and wrote the episode just for that. The series never properly recovered, and disappeared into a different (and silly) world the next series.

(And I disagree with "Two Cathedrals": I prefer the double episode which opened series two. Two Cathedrals tries too hard. )
