DOUBLE SPOILERS!!!!
SPOILERS (obviously)
It was okay. They played it a tad safe. The governor's villain luck holds out, folks panic instead of shooting back, I can accept that since they were shocked by his actions and not fighters. But it's a good thing his closest men are loyal even when there's no reason to be. Seriously, neither guy had any feelings for any of those people? They think a snapped Philip isn't gonna take his anger out on one of them at some point?
Andrea...taking on walkers with a knife...can't handle one sans knife? She was too intent on getting her other hand free, that's where I think she blundered.
Why stay in the prison? Why no Woodbury...they were asking that on Talking Dead...no one had a good answer. I'd imagine there's tons more supplies in Woodbury, and far more comforts.
The Governor's two surviving henchmen going with him was such a hilarious moment to watch, but as you said it didn't make sense. They obviously DIDN'T want to get in the car, but did anyway, even though the Gov was out of bullets. As for Andrea, I'm guessing her inability to kill Zombie Milton was due with her physical state... we don't know how long she was tied up in the torture chamber but it must have been a couple of days. Lastly, Woodbury vs. the prison... I guess the prison
might be more secure? Or at least they might need fewer people to defend it/guard the fences?
Overall I thought the finale was good. I liked Andrea's character, mostly due to how imperfect she was, so I was sad to see her go. It was a terrible way to go out, fighting a zombified version of a friend and then shooting herself in front of her friends. Interesting that she ultimately committed suicide. The prison fight was anticlimactic, but the Governor mowing down his own troops was quite unexpected. Having the Gov just drive off didn't seem to fit the overall tone of the finale, but I'm glad he is still alive. I'm guessing he will run into Randall's group from Season 2 and end up with a dangerous fighting force.
Lastly, there were too many suspenseful moments in the episode where I expected stuff to go down, but it didn't. In particular when the prison group was just standing around in the courtyard after ousting the Woodbury Army, I fully expected a straggler to shoot one of the good guys. When Glenn first took off his helmet I was on the edge of my seat, I was ready. Then with Milton's turn, they did a great job drawing that out. I was also expecting Tyrese to burst through the door to save Andrea, but obviously we know how that went...
Bring on Season 4.
