These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Dead Set
Moral Event Horizon: Patrick the producer is pretty mean from the get-go, but to really hammer this home the first episode shows him throwing a man in a wheelchair into the path of a zombie.
Nightmare Fuel: The final shots of zombie Kelly staring directly at you through dozens of TV monitors will haunt you.
