The Walking Dead is awesome!
Anybody who has taken an interest in zombie related entertainment should check out AMC's "The Walking Dead", based on the long running comic series of the same name, directed and mostly written by Frank Darabont. Director of the Shawshank Redemption, The Green Mile, and The Mist, all great movies.
I don't think it was Merle. He seems more the kind to show up with a gun, not the type that would think to lure zombies to the others. It was probably just them maknig too much noise over time. that car alarm probably didn't help.
My wife and I were really disappointed with the under-preparedness of the campers during that attack. What the hell? Within a day of a zombie apocalypse i would set up terrain defenses.. FIRST THING when making camp. We would have high ground, a defensible position, and everybody would know exactly what to do, just like a fire drill, if... no, WHEN the zombies show up.
I understand people had to die in that scene to push the show forward, i just wish that they would have looked like they had some kind of plan for dealing and it just didn't work as well as they would have liked. instead it looked like everybody was surprised that there were zombies in the world.
Wife beating red-neck. "Oh, hey! You're not my wife. Say, what happened to your face? It looks kinda dead or something."
Zombie "NOM NOM NOM NOM"
He didn't even try to scream and warn everybody, or even in mortal terror.
I did some research, skip the below if you don't want to get a potential spoiler.
In the comics it is later revealed that the virus has already infected everybody. The virus itself doesn't kill people. The bites are like Komodo dragon bites, they cause lethal infections but it isn't the Z virus that takes the people out. At one point in the books, a person is killed by another survivor and they resurrect without having been bitten. I think that is part of the reason Jenner would be so "sad cindy" on everybody.
