Young Guns is best watched in the playful, none-too-serious spirit in which it was made. Though the film concentrates reverentially on its young stars, it also includes good performances from a few grown-ups, notably Terry O'Quinn as a lawyer and Jack Palance as the story's wild-eyed villain.

Considering how tidy and self-aware most such Hollywood projects are, any movie that can give Phillips' Mexican-Indian a monologue in which he painfully recounts the massacre only he survived and then blithely rejoices in idiot gunfire is a movie you have to respect. [12 Aug 1988, p.35]

To say Young Guns is one of the best big Westerns of the '80s doesn't mean much: Westerns have been almost moribund since 1976. But it does hint at this movie's surprising vitality, bloody ebullience and violent impetuosity-qualities it shares with crazy little Billy. [12 Aug 1988, p.11]

Young Guns is really a modern action movie in the revenge mode, disguised as a western. But with all its faults, it more or less works. Palance is a great heavy, Estevez makes an off-the-wall hero, and there's usually enough happening on screen to keep you interested. [12 Aug 1988, p.E3]

YOUNG GUNS is simply not a very good movie--western or otherwise. Fusco's script provides little character development and muddies the narrative with some unlikely supporting characters. Still, it proved to be popular enough to lead to a television spinoff and a sequel in 1990.
