I mean, it’s bloody, as in baddies die and it’s graphic (which violence is). It’s Denzel doing his best Denzel; the opening sequence hilariously exposes his OCD by having the lad use a toothbrush to manicure his sneakers. You see him at work in a Walmart factory or whatever and he’s dedicated to the job. You get the feeling he’s hard as nails, though. And he turns out to be in the most Denzel way feasible.
The antagonist has a personality and is interesting; this is a rarity in the current action-thriller landscape. The soundtrack/score also works.
And Denzel utilises a nail gun.
Also, I’ve never seen the Edward Woodward TV show. It’s too late now to bother with it.
Wanderings and ... wonderings.
