zombies here are not those almost impossible to be killed by a zombie from walking dead and other decaying zombie that can still hear and smell. instead they use more realistic zombies in this tv series where humans have been infected with some virus that triggers when u are near on a dying state or dead and it seems adrenaline is constantly active and zombies are rabid thats why they still have some sense of a normally alive human like sense of direction hearing and maybe smelling....but no stategical capacity makes more sense to me than decaying zombies that has sense of smell , sight and hungry. but the story in the first episodes of the series is kinda slow and boring not enough sense..maybe because people dont know how to deal on whats happening around them and is kinda new to them because maybe they watch too much walking dead and believed its how zombies shoud be ... weak decaying and slow.. but no they are not.. instead they are strong like a human pumped with adrenaline and feels no pain and is just undying.. at episode 5 in the dinner they realize this they need weapons real once and so try to slow them down and then aim for the head. sadly the gun in their possession has only 2 bullet for 2 bloodlust trashing zombies. if u play game u know this when u have been caught off guard or by a charging zombie ..so first shot is to shoot as fast u can.. but make sure it hits them (upper chest easy target might even hit the head) stop them from approaching u and have enough seconds to aim for a kill shot to the head. after all in reality more that half of us didn't ever held a gun. guns and bulllets are not plenty around and so are baseballbats. kitchen knife are plenty but they are not built to harm an undying human.
