Zombies. . .
Okay, Dawn of the Dead zombies were kinda typical. You know, walking dead, always after humans, shuffle slowly around (most of the time) and make moaning noises. Created by 'something in the blood'. Get bitten, you die and turn into one. Nothing really that interesting or original about them. But then it wasn't really a good movie. . . A little too typical. :P And why did they spent most of thier time in a mall?
Shaun of the Dead's zombies were the same thing, being a rip-off of Dawn of the Dead. . . Except they were much funnier and therefore much better.

Better movie. And I loved the way they found ways to use the walking dead at the end of the movie. :P There were parts of Shaun that were nicely done, too. Like this below:

28 days later's zombies were a lot more interesting. Except they technically weren't zombies, since they were living people who had been infected with a virus transmitted in blood and siliva called 'rage', which caused them to go into a non-stop killing frenzy, and vomit blood everywhere.
The thing about them was the fact that everyone waited for them to starve to death. But the problem with that is they couldn't drink anything, yet they were vomiting blood everywhere AND kept moving really fast.
Wouldn't they have de-hydrated very quickley? But then if it was like that, it wouldn't of made a good movie, so there you go. :P
Doom 3's zombies. . . Now they were what I'd call typical walking dead. :P Hell invades a research base on Mars, everyone gets turned into zombies as thier souls get stolen. Hmmm, nice.
What I don't get is that non-security personell were the slow, shuffling lashing-out-with-hands type (some with no heads), while the security personell (people with guns) were all fast, talked in Romeric (or some other ancient language), and could roll around, shoot you with thier weapons and take cover behind boxes and stuff as if they were normal humans.
There is a particually weird scene in Doom 3 where you can listen to some physicatric(SP) doctors trying to interview a guy who is slowly turning into a zombie. Kinda disturbing. o.o
Anyway, I know this is fanboyish, but the most original zombies I've seen have to be from Half-Life 1/Half-Life 2. Headcrabbed humans.
Okay, Headcrabs are parasitic alien creatures that invaded Earth with loads of other aliens when Freeman (The character you play in Half-Life 1/2) accidently opened up a portal to a borderworld called Xen.
They latch onto thier human hosts, changing thier DNA structure, taking over thier central nervous system, and mutating them so their hands and arms become long, red, with sharp spikes, and then since they can't eat anything through thier mouths, a slit appears down the center of thier chests with teeth and stuff. :S

Half-Life 2 enemies:

The thing is, thier human hosts remain alive during this process, put into some kind of sub-concious state where all they can hear is thier own screaming, blinded and controlled by the headcrab stuck to thier heads. And they feel pain.

Perhaps THE zombie growl of the century? I've played the game twice and listened to them scream as I burn them, but they still disturb me.
Of course there is a lot more then Half-Life zombies then I've said here, and a lot of speculation behind them, but I think this post is long enough. :P And I'm tired.
