This is an entertaining B-movie bolstered by performances from a cast that often rises above the predictable material.

Stallone provides just the right amount of world-weary gravitas and deadpan humor to put over the hokey material. And he still has the requisite imposing physicality to make the sight of his character beating up men a quarter of his age fairly convincing.

Those who remember a time when afternoons were spent pumping quarters into Street Fighter II and fantasizing about Sylvester Stallone beating up your bullies, will no doubt feel a surge of nostalgia — and a healthy dose of dopamine — watching Samaritan.

Samaritan is basic enough that it often plays like a video-game film in which someone forgot to add the CGI. But the movie builds to a very good twist, and Stallone, in his way, brings a vibe to it, complete with an ’80s kiss-off line (“Have a blast!”) delivered in a growl so deliberate it practically etches itself into the scenery.

In a movie world crowded with everyone eager to make their own special superhero stand out, this one doesn’t pack much of a punch.
