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: Hell on Wheels
Arc Fatigue: The Swede's rivalry with Bohannon is starting to wear a bit thin for some people as of season four.
Broken Base: The show's pretty much split the audience in half since its airing.
So Okay, It's Average: Many, if not most, critics feel this way about the show. Being that this is on AMC, and that this series followed in the wake of the highly contested The Killing, this was not a good thing.
Special Effect Failure: Cullen finds a photograph where the face of the man who ordered his wife hanged is blurred out, in what is clearly a cheap Photoshop effect rather than any of the issues affecting photography at the time.
