It would've been a decent 7 or so if it was a regular episode. As a finale, and as a payoff to the Woodbury/Prison arc, it was the worst episode of the show to date.
Yeah, just watched it. Really anti-climactic. The Governor's 'troops' were complete pussies ("Argh! I think I saw a zombie!"); Andrea exceeded her own stupidity ("Don't worry, Milton, you'll be fine, it's just multiple stab wounds in the gut. There's no need to rush picking up those pliers you gave me with your last act in life"); and they all still have Star Wars Stormtrooper aim, which makes for pretty boring gunfights (seriously, they might as well just run around shouting, 'pew, pew, pew!' and making explosion noises.)
I think Andrea annoyed me the most. After about fifteen minutes of shouting, 'PICK UP THE FUCKING PLIERS!' at the screen, I started rooting for the pliers. I think they pretty much outwitted her. In fact, they're now my new favourite AMC's The Walking Dead
Let's hear it for the pliers! They did what the Governor and like a million zombies somehow couldn't do: killed this pointless insult to a cool comic book character. Good riddance!
