You'll need to move fast, but there's an interesting discussion going on in The Corner blog at National Review Online about The Invasion. Jonah Goldberg initiated it, and I think his understanding of the film is pretty accurate, if a bit imperfect. Goldberg seems like a bit of a film nut; he once wrote a cover story on the metaphysical genius of Groundhog Day. Mark Steyn is in on the discussion, so something amusing is bound to be said.
As you might know, The Invasion was close to my top 10 list for last year, probably somewhere in the 11-12 range alongside Into the Wild and The Diving Bell and the Butterfly.
