Spoilers abound, read at your own risk:
The episode was decent, setting up for another season - nothing too shocking and the story is basically just trying to keep going. Each season has captured a different point in their survival, this one picks up a few months after the Season 3 Finale with the Governor. I liked how the prison yard became more of a farm and (parts of) the prison had become more fortified.
It's pretty clear that the fence is going to be a big problem this season. As much fortification was done around the gates of the prison, they should have extended that to the fence itself. If they put those big ass wooden spikes along the problem areas of the fence, the walkers would just impale themselves, creating more of a barrier for approaching walkers. Also, a moat or random pits would be much better fortification than relying on the existing fences. Also, letting the little shit kids stand on the perimeter yelling at the walkers is probably a dumb idea.
There is a influx of characters, which is what was needed to refresh the show. "We need more victims!" says one TWD executive. So the prison has multiplied times 10. Bunch of no name characters sucking the d's of the main cast; the ones without names will eventually be sacrificed to keep the season moving. I imagine a good amount of them will be gone next week. By the end of the season, it will only be the main cast with a few random stranglers. Too many characters doesn't really work well in this series.
"We need more relationships to tug at people's heartstrings!" says another TWD exec. Everyone is hooking up. Glen and Maggie are still banging and thinking about kids - but mostly how they don't want to have them. Glen needs to give her more facials to prevent the inevitable child that is going to come along sooner or later (season 5?). The big black dude from last season (who also looks like my Franklin from GTA) is swinging mad dick, though it's only implied. I thought the one black chick was his wife, but I guess that was just me being racist because he's slinging his black snake at the incredibly hot spanish chick. Maggie's little sister, the blonde chick is hooking up with some doofus zombie bait, but she's already lost her mom, brothers, etc. so she doesn't give a fuck. Also, Daryl and the lady who's hair should have grown in all the way by now (Carol?) are also destined to bang or are already. I will be surprised if she makes it through the season and that will make Daryl sad and vengeful - which is when Daryl was a good character. All of the little girls are too young for Carl, and after the conclusion of last night's episode, I don't think he'll be getting gay with the nerd that wanted to suck off Daryl.
The beginning of the episode felt like a "where are they now?" segment, nicely updating everyone and establishing their ranking in the prison's community. There's a council and a bunch of people trying to impress the council. It should be noted that all of the council is white and all the black people want to be accepted by them. Herschel some how got some magic prosthetic leg that eliminates him having to use crutches or for the special effects department from cropping off his leg. Rick's still crazy, Daryl's still a badass, Carl's still a twit and Glen's eyes have become more slanty.
The big event in the episode was a run for supplies where disposable characters want to prove their worth. Daryl's the leader, Michonne happens to drop by as they're headed out; Glen's in; they throw in a few more black people - including one with a drinking problem who has to beg to be a part of the team and promises to not mess things up on the trip; the doofus young kid, and a few other randoms. Luckily, there's no zombies at the store except a couple at the front door - Big Spot greeters working overtime, no doubt. That drunk black guy should have known that the roof was FULL OF ZOMBIES by the random crotch hanging around outside the store. Of course, things can't go to plan. "Stay in formation, get what we need."
While in the store Glen foreshadows the impending baby. The stereotype black person can't deny the temptation of shitty wine and causes all the zombies on the roof to come crashing through, along with the helicopter that had been apparently carrying the 50 zombies/people that were on the roof. The zombies crashing though the roof was great; especially the water-balloon zombies that were all mush and the one getting hung up on his intestines. Of course, the fallen zombies bite and bullets are fired and almost everyone gets out alive. The blonde chick doesn't give a shit that the doofus did not return and simply changes the "30 Days Since our last accident" sign to "0". What a cunt.
Meanwhile, while all this is going on, Rick goes on a vision quest and follows some skinny ass lady to her "husband" to have them come and live at the prison. But just as Ackbar said, "It's a trap!" I guess her husband was a zombie or something. It didn't show it, which was a total copout. She wanted to feed Rick to her pet zombie husband and just decides to seppuku her self instead. Rick should have taken her Coleman tent and sleeping bags, which seems to keep walkers away.
Anyway, at the end of the episode, Carl's potential boyfriend starts bleeding all over the overly creepy prison bathroom. His eye periods are identical to the zombie Rick kept focusing on with the fucked up eyes outside the prison. There is a good chance this season will introduce some new disease that people can get from having gay sex with a zombie, which is likely how the nerd got it. He also gave it to the pig, Violet when he had sex with it.
Anyway, I will try and review each episode this season. Hope you enjoy.
