The premise of the film seems like it would make for a tight, intense thriller, which is unusual for the Western genre, which is mostly known for languid pacing (and I mean that in a positive way). But The Stalking Moon moves so slow that it became a chore to watch.
In a more contemplative or thematically driven Western, this pacing would have been more acceptable. But for what is essentially an action thriller, a pace this slow is basically the kiss of death.
Gregory Peck is solid, as he just about always is, and I've always liked Robert Forster so his presence is much welcome. There's a lot of lovely desert scenery, and the film is well shot. But this is ultimately an average Western that fails to make much of an impression.
