First of all I think you guys should have think more realistic about the movie let us think it is realistic like the walking dead how the zombies are the outbreak . In the movie I mean the zombies are literally half alien and half monster like their eyes the blue stuff that came out of them when they got shot and the way the zombies moved looked like the way the vampires in twilight moved and there are some scenes that looked fake the scene where the helicopter went out of the city when the bomb exploded .but overall I just liked the characters that played in the movie .
