When The Resistance attacks and Tex fires his automatic weapon, 'Commander' reacts to the firing weapons in the background after ten-plus seconds, a significant delay.
Early in the film when Tex and Eve are speaking, one can see their breaths as if they are in the cold, yet the visible breaths are inconsistent.
In the 44th minute when the Commander is fighting Brad, Brad punches him and the Commander slides, standing, across small pebbles. The punch might knock him down, but not send him sliding backwards in a standing position.
When Eve calls her combatant halfway through the movie by twisting his head sideways, this would be virtually impossible to be lethal. Unless perhaps he was surprised or taken at an angle, the victim's neck muscles would protect them from death. If anything, the attacker would need to twist the victim's head UPWARD.
In the 25th minute one of the zombies walking up the stairs wears eyeglasses, which seems odd.
Beginning around the 23rd minute, both Tex and Eve take odd aims at zombies. Tex appears to shoot his victim either in the ground or between the zombie's legs. Eve aims her weapon too low to be aiming for either the head or torso, which seems odd.
