Great episode.
So far, they haven't quite made the Governor evil enough, though. Maybe that's been their intent. Maybe he hasn't completely cracked quite yet ... and the worst is yet to come. Or, maybe he's an ambiguous villain (I haven't read the comics), sort of a slightly darker mirror image of Rick, rather than a truly evil villain.
Still ... I kinda get the feeling that he's the villain right now because we've been told he's the villain, and we're more invested in his opponents. Watching the Penny scene without foreknowledge of who's supposed to be good and who's supposed to be bad ... you'd have a hard time coming out thinking Michonne was the hero.
So far, they've shown the Governor to be creepy -- biter heads in aquariums, zombie daughter in the closet. But, that's not much creepier than Daryl's walker ears necklace, Rick's walker-killing rampage in the prison, or Morgan's zombie wife in the lawn (at least Rick didn't shoot the wife in the head while Morgan was pleading with him not to). Good guys have done the same thing.
They've shown the Governor to be ruthless and maybe murderous -- the National Guard detachment, sending a scout team after Michonne, torturing and potentially executing Glenn and Maggie. But, that isn't all that different than Rick's group's treatment of Randall -- torture, scout teams chasing, planned executions. Or the prisoners ... Michonne has been at least as much of a threat to the Governor as that ass-clown prisoner Rick macheted in the head. It is arguable that she's done more to the Governor than he has to her. She's definitely done more to Woodbury than Randall ever did to Rick's crew.
They haven't done enough to differentiate Rick's team from the Governor's. I'm not sure Rick or Daryl wouldn't have done some or most of the stuff the Governor has ... protecting his own. Maybe they will in the future.
Still. Great television.
