!!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.

!!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.
