Finally got around to watching it this afternoon.
Great, heartbreaking episode, although I don't think it's quite as emotionally wrenching as the episode last season when T-Dogg and Lori both died, but it was hard to see Herschel go out the way he did.
Few more thoughts;
Anyone else wondering what happened to the younger sister (of the duo the Governor ran into the last couple of episodes)? I know she went shell-shocked or whatever you want to call it during the battle and wandered off somewhere, but since they didn't show her die, I have to imagine she's alive. Same with the older sister who shot the Governor at the very end.
I'm surprised no one has commented on the total badass-ery of Daryl using the zombie as a human shield in order to use that grenade to devastating effect.
One last thought...I'm sure I'm in the minority here, but I found myself hoping that Michonne would get off'ed. I do not like that character. In fact, I would make the argument that she's a villian herself; not as much a villian as the Governor is (was?), but a villianess nonetheless. She didn't have to kill his original zombiefied daughter; the girl posed no threat as long as she was chained up and Michonne did it out of pure hatred of the Governor, which started his descent down into true psychopathic madness. Again, I'm probably the only person who watches the show who feels this way, but I'm really hoping she gets killed off soon. That's a death I would cheer.
