My zombies - what i want from them

well, after doing a bucnh of reviews of movies, looking at zombies and reading about them, maybe i need to lay out what im looking for in a zombie.

To me a zombie must be uniform, one zombie cannot be smarter than others, they have to be lifeless, dead in the eyes, they do not register that their is a human standing in front of them but instead register food. they are slow, they creep forward limping, stagaring, forever after their prey. they are unintelligent, they do not possess the ability to think or even talk beyond a moaning, or for comic effect "brrraaaaiiinnsss".

My zombies are to be feared on teh basis of infection, there is a simple method to figuring out the infection rate: you get bitten = 2 hours = dead = 1 hour= zombie! so 3 hours is your time limit, to kill one. once zombified they wil live for up to 10 years depending on factors such as climate and environment.

but overall, my zombies are to be generic, even though they are the walking dead i do not want them to be seen as really scary, they are a product of imagination, i am not implying that they are in anyway real, they have to be seen as objects of a story. they are all to be similar, similar height, weight, build. there will be minor differences but nothing too substantial, they will be seen on a individual basis as well a hoard, they will be seen as never ending, much like it would be if there was a zombie apocalypse, to begin with you would be looking at the zombies as individuals sympathising with them, trying no to think about what they had to live for before smashing their head off. no, as time goes by the zombies would turn into this generic mass, you would stop caring about them, stop thinking of them as people and just a singular entity, mush like a mosquito or a cane toad... just much larger.
