Sure, Denzel lives in one spot and isn't a nomad like Reacher is in most of the books, but there are so many Reacher elements:
-
Random "Lemme go into the local drug den" and push everyone around
-
CIA betrayal after betrayal until it's absurd
-
Aging hero who can still murder anyone quickly with their bare hands, and is really never in danger
-
Hero who barely has any skin in the game but goes on elaborate murder missions because he can.
-
The non-Reacher elements (the drama with the wife, drama with neighbors, drama with kid) is more Reacher-esque than all the awful long out-of-place kid-rearing scenes in Jack Reacher 2: Never Go Jack
-
It's never much of a "Will he succeed?" scenario in any Reacher book I've ever read. As in, he doesn't get beaten up and kidnapped much, rarely starts from a long-shot perspective. It's like the Equalizer, he just find information and becomes unstoppable to get the next information, moving up the chain until his unstoppable final fight. Not a lot of ticking-clock omg! tension moments, just watching someone pound and stab and shoot their way through paramilitary guys.
Solid movie. Different from the first, but still legit.
