- Adaptation Displacement: The show currently has a higher profile than the series of books that it was based on.
- Alternate Character Interpretation: Jacob Nighthorse offers ground for a great deal of it, including in-universe, especially in later seasons. Is he a basically good person genuinely trying to help his people using unscrupulous and shady methods? A greedy businessman who preys on the Cheyenne Reservation and offers more harm than help to its inhabitants? How sincere are radical politics, and how much are they a hypocritical shield for his ambitions? Is he right to try to invest the money from his projects into infrastructure to help the Rez long-term instead of dolling it out directly to its residents, or is he demonstrating exactly the kind of arrogant Condescending Compassion that the U. S. Government once did in dealing with the Cheyenne (and to some extent still does)? Even his allies have different opinions on these subjects - and that Walt loathes him and thinks the worst of him in almost every situation doesn't help.
- Fridge Horror: When Longmire tries to convince Dr. Weston to change the cause of death on Branch's death certificate, the doc says Longmire will need more evidence than dirt in a shotgun shell to convince a court to change it. Considering Longmire is the only one to hear Barlow's confession, and Barlow is now dead, it's likely Branch's cause of death officially remained a suicide. To add insult to injury, the Connallys seem the type to have a family cemetery plot, so it's also likely Barlow is sharing a grave with his murder victim.
- Moral Event Horizon: Malachi was always a Dirty Cop, but he proves once and for all just how evil he is when he murders one of his own men when he tries to back out on killing Hector.
- Nightmare Fuel: David Ridges, especially how he methodically breaks down Branch Connally's sanity.
- Chance Gilbert. Truly puts the Crazy in Crazy Survivalist.
- Ooh, Me Accent's Slipping: The Cheyenne Malachi and the Crow Medicine Woman are played by Graham Greene and Tantoo Cardinal, who are both First Nation Canadians rather than Native Americans. There's a hint of Not Even Bothering with the Accent mixed in, because they're doing little to hide their rather thick Native Canadian accents, probably on the assumption that most viewers except Canadians and Natives from both countries can't really tell the difference.
- Screwed by the Network: Despite being one of their most popular shows, A&E cancelled it after the third season due to being too expensive and having viewers too old for their desired demographic. But it was later renewed on Netflix and ran for three more seasons with the sixth slated to be the final one.
- The Woobie: Tamar Smith, full stop. A war hero suffering PTSD after being violated by her superior officer, she can barely function in normal society. And when she sees her therapist taking up with a male authority figure she kidnaps her, so damaged that she cannot distinguish between Walt and the man who abused his power and raped her, and desperately tries to protect her by dragging her to a secluded cabin against her will. Later, after seeing several sensationalist stories about her supposedly being in a lesbian relationship with Donna, and being gently talked down by Walt and Donna, she walks out to her dock and tries to commit suicide rather than be arrested.
