!!The books:

* FridgeBrilliance: As a general rule, Reacher is in peak physical condition and at the top of his game. Which doesn't make sense, because he's technically retired. But he's naturally built very strongly, spends his days wandering about the country, sees action every time a story comes up, and and sometimes this is actually explicitly noted as not being enough.
* MartyStu: Reacher can tend this way at times - it's particularly pronounced in those volumes of the series which are written in first person.
* NightmareFuel: Reacher's claustrophobic attack in ''Die Trying'' is terrifyingly realistic.

!!The film:

* HarsherInHindsight: The movie starts with TheDragon sniping five innocent bystanders. Then came Sandy Hook Elementary School massacre, forcing the movie to delay its red carpet premiere.
* {{Narm}}: Might be the only time you'll hear someone in a modern film actually say, with no hint of irony, "I'm not a hero. I'm a drifter with nothing to lose."
* NightmareFuel: Werner Herzog as the Zec manages to be completely terrifying despite not really doing anything but talk for the whole film. All he has to do is be himself, the CrazyAwesome director who seriously considered an offer to kill his lead actor, made a film on an active volcano, and ate one of his shoes.
* OneSceneWonder: Robert Duvall as the one guy in the world who can converse on Reacher's level.
* TaintedByThePreview: Fans of the books were livid about Tom Cruise's casting, as he looks absolutely nothing like the Reacher of the books (most notably, Reacher is huge, and his size is often an important part of his characterization).
* WTHCastingAgency: ''Creator/WernerHerzog'' plays the BigBad?
** IntendedAudienceReaction: That's more or less what the BigBad was going for.
