Solid episode, nice to get something new-ish, although I have a bad feeling we're just eventually waiting for a huge horde of walkers to destroy the town. Hopefully they can pull this off, but all the zombie film clichés are definitely there ready to be used: everything from the mad scientist experimenting on the zombies to the "unpenetrable" fort. The Governor seems to be a collector of things; if you noticed he had put Michonne's sword already on display.
