A show where they spend more time developing new characters that didn't exist in the game, only to kill them off.
A show where characters that's are given backstory don't even interact with the main character.
A show where an entire episode is another characters backstory instead of showing the trials that could have ensued in present day
A show where every kill is off screen or implied.
A show where you forget the Cordyceps is a thing due to lack of infected or evidence that the infection is there. What few infected have appeared haven't even interacted with the main character.
A show where for 2 episodes I didn't pay attention but wasn't lost as nothing changed.
A show where the 2 main characters have jumps in development rather than a steady progression. It goes from "I hate you" to "I respect/like you" in the space of a day.
A show where if you've played the game, it's a huge disappointment but if you haven't, it's a nice story about 2 people going for a long walk and on occasion, doing something else but nothing eventful.
Even mimicking events in the game is boring and those are few and far between.
The first episode where its shot near enough frame by frame is a lie. After that, nothing is the same.
