The Walking Dead is pissing me off so much, you have no idea.
I mean, where does the infection came from? Why is everybody infected? How did it spread all over the world? How does the infection work?Why is it only affecting humans?
Why are the brain cells not dead? Does walker’s heart pumps blood? Why are they breathing? Where their muscles take energy required for chemical reactions so they can move? Do they take energy from the meat? How do walkers digest the food to do so? Do they use enzymes? Do they synthesize enzymes? How do they keep proper body temperature and pH for enzymes to work?
…but most of all …why did that little zombie girl from the TV show pick up her teddy-bear???
