Ofcourse the movie theme is fiction, but could have at least ended more dramatically rather than having such stupid solution to the epidemy of the zombie story.
Gerry Lane [Brad Pitt] a UN employee is no scientist. I accept the fact that he notices zombies ignoring 1 or 2 humans without attacking them, but then he tells his own theory to scientists, about some people being camouflaged to zombies, and reason that there should be a formula to vaccine all people to become camouflaged.
Unbelieveable the potion already existed [scientists did'nt know it LOL] and was in a zombie infested lab. When he successfully gets hold of loads of different bottles of different potions he does'nt know which is the right one [if ever it proves to work]. He picks one out of so many and injects himself.........and poof in a minute he was invisible to zombies. It's true in a movie you can lie as much as you want, more and more being a fiction movie, but this I find too stupid and too childish.
