That "apocalypse" is something that can happen without reducing survivor's access to enough clean water and fabric to not only create goofy looking, over-shouldery, WHITE Templar uniforms, but also keep them absolutely spotless on a daily basis, with nary a bit of dirt or - as one WOULD expect - gobs of bloodstains reducing their utter purity of appearance.
That cars lacking visible solar panels can run as well as do all those murderous tricks, suggesting easy access to gasoline, ammunition, tires, batteries, and engine coolants. (Remember Captain Jinx from "Call it Free?") despite this being a post-apocalyptic wasteland.
That in said wasteland everyone surviving the nuclear apocalypse somehow can manage to find enough to eat and drink without looking noticeably sick or scrawny - at least physically.
Apparently they also have plenty of hair product - say what you want about the sick minded Templars and their goofy hairdos, their hair is always clean and well cared for instead of going into matted dreadlocks or even looking dirty.
Two men and one spunky 8 year old can take out an entire murder cult in less than a day or two.
Stepping on a bottle of blue food colouring will make it explode~!
