The filmmakers do not trust the audience to grapple with these plain elements alone, so they add unsophisticated humor... Whatever life Brosnan tries to infuse into the proceedings is undercut by everything that surrounds his performance.

Corny, yes. But charming, too, like when a nurse delivers a mini-monologue of reasons Artie’s too ill to travel that plays out like a clown car of ailments.

Despite Brosnan's best efforts, this is a movie with its heart in the right place and its head somewhere substantially other.

If you are worried that “The Last Rifleman” will be another movie centering an older person but actually insults their intelligence and does not adequately represent their experiences, don’t.
