This was the kind of episode I've come to expect from great series'. Edge of your seat - not sure what is going to happen next - anything goes. Love it. Pretty much every episode of Breaking Bad was like this - but I digress...
On a critical level: Why the hell didn't Rick send some shooters out of the prison to outflank the attackers? They could have set up two or three people in the woods while he and the Gov were talking - and when the shooting started they could have caused an awful lot of chaos and done some major damage - that group wouldn't have any idea how many people were in the woods behind them, and with bullets flying everywhere, I don't give them much of a chance. Not to mention - someone should have immediately sniped the Gov if they could have.
The Gov confused me by killing Herschel - I thought for certain he would take out Michonne first. 1) He has a personal vendetta against her. 2) Herschel is infinitely less dangerous should things go south - eh - which they did. Sorry, Gov - that was a bad choice. Michonne is awesomely lethal. YEAH!
I know it's television and perhaps I missed something - but I don't recall there being any vehicle down there for Rick to duck behind when the shooting started. I don't think even poor shooters of that number could fail to put a bullet in the one target directly in front of them. It was a bad move for Rick to get into firing range. Tactically, if I were the Governor, I would have shot him dead straightaway and demanded to speak with someone else. With the hostages in peril and their leader taken out, that really ups the ante for those in the prison.
We should start up a Dead Pool for this show. IMHO there are only two characters that they won't consider killing off. Rick and Daryl. And I may even put Daryl ahead of Rick in that category. Herschel has been on the bleeding edge (sorry) of being killed off for quite awhile now - so I'm not surprised his number came up. Knowing that a show has no problem killing off major characters is scary but certainly adds to the drama. The challenge will be for the writers to continually introduce new, likable characters that the audience can become attached to.
All - around stellar finale!
