I welcome correction from others who've seen it, of course.

(This seems to be a movie that's hard to really encompass in one's head. The Washington Post's review seems to think that Harvey Dent will be appearing in the next movie, and the Locus spoilerific essay thinks Lucius's typing his name was his resignation, not the destruction of the espionage machine. If the (semi-)pros can get all that wrong, I can certainly be wrong about this . . . )
