There are several instances of lack of continuity between wet and dry scenes. In one scene the main characters bath in a stream, getting completely wet, yet moments later they are driving on a road and are completely dry.
At 44:35, the characters are outside a building. One says she will check inside and the camera cuts to the other just before someone walks across behind her. It is only a brief glimpse, but the nature of the story makes it inexcusable.
The two main characters are trying to be quiet, trying to be very careful to avoid zombies, but in one scene they bath in a stream, laughing, having fun, without their protective weapons nearby. This seems out of character related to their previous efforts to be careful.
After returning from an expedition, the characters remove several weapons and continue with only a baseball bat and a pistol. After a zombie encounter in which the pistol is lost, one then stabs a zombie with a large hunting knife. Given the clothing they are wearing, one wonders where the character concealed this knife. They then go off to confront an unknown number of zombies with only the bat, leaving countless weapons untouched in a room nearby.
