Law Abiding Citizen (2009) is a psychological vigilante thriller directed by F. Gary Gray

What Falters

A sequel has been in "development hell" for years, with Gerard Butler repeatedly expressing interest. Until then, the 2009 original remains the gold standard of "justice-gone-wrong" thrillers.

Act III: Nick Rice realizes he isn’t fighting a standard criminal. Clyde has used his engineering genius and years of solitude to build a network of tunnels, traps, and remote-controlled weapons. The film climaxes in a tense standoff where Nick must decide whether to negotiate with a monster or find a loophole in Clyde’s perfect plan.
