Did anyone see the final episode of Walking Dead?

I wonder when it will resume. I just have a question concerning the plot. Dr. Jennings showed that the brains of the walkers are dead. Only the brain stem rejuvenates. Since the brain is already dead how can shooting it destroy the walkers? That seems to be a weakness in the story line Maybe the writers can come up with a plausible explanation. Ok, I know it's just a science fiction show, but I like it and a little critique won't hurt.Did anyone see the final episode of Walking Dead?
In most zombie films you kill the head then the undead dies..again. Because the brain is what has all the nerves to keep the zombie moving/functioning (walking,crawling,biting etc..) and when the brain is shot it destroys the nerves.

I think this show is awesome, i think it's pretty realistic, and the zombies aren't those corny zombies.

I think the acting was pretty good too, only problem is, season 1 ended too soon.
The stem, where the basest functions are carried out is reanimated. That helps to explain why it doesn't take total destruction of the brain to down a zombie in the series. As long as that part is destroyed, it's lights out permanently.Did anyone see the final episode of Walking Dead?
the brain stem is the "lizard part" of our brain. any trama to the rest of the brain, such as by gunshot would be enough to permenantly damage the stemDid anyone see the final episode of Walking Dead?
I really like the show, but the plot is a little thin and the acting is complete shite.
dumb question.. watch it again the doc explains it and yes i agree the plot is too thin and the acting has been quite weak.. but I will continue to watch it probably
