Wow. Now THAT is how you end a season! It was like Zombie-Palooza. So many great moments:
-The mysterious helicopter.
-Hershel being badass and defending his farm. I seriously thought they were going to have him killed off, but I guess they're saving that for season 3, probably to show how dangerous the prison is going to be.
-The barn burning and falling down.
-The mysterious woman with the sword who saved Andrea.
-Rick telling everyone what Dr. Jenner said at the end of season 1, and confirming what we had all already assumed: everyone is already infected.
-Rick finally being the man.
Also, I find it funny that T-Dawg spends an entire season doing nothing, and the one time he actually has a scene, he says the completely wrong thing (wanting to go east instead of going back to the highway). Idiot.
I'm surprised Carol didn't die. She's useless.
I'm not surprised they killed off most of Hershel's children. The only one that adds much to the show is Maggie, the rest are just cannon fodder. What was the name of the one blonde who survived? Was she the one who wanted to kill herself? I hope so. She was the only other one of Hershel's kids who actually had a story this season.
Overall it was a great season, and a HUGE step up after the midseason break. They said on The Talking Dead that for next season we can expect the same quality as the previous 3 episodes, so that just builds the anticipation even more.
