While it doesn't offer any answers, it both thrills and makes you think.

Excellent and certainly provocative... If nothing else, the film is a real conversation starter.

Close shines in drama with strong language, adult themes.

Worth seeing just to witness how winsome it is.

There will be a large clientele that will like the new Fox five-reel melodrama, "Western Blood." Tom Mix is the hero of it and Victoria Ford gracefully fills the second part in the love story. Besides this, it plays up humorous situations in a way that will be liked by many. It is undoubtedly a little too long, though it works steadily toward an exciting and interesting wild west climax with dashing horses and smoky shooting. One unusual situation is that of the cowboys all in fifteen-dollar evening suits at a party just before the ranch is raided by Mexican bandits at the instigation of Phul, the German agent. The direction by Lynn Reynolds of these out-of-door scenes is much abler than his work in the society scenes in the early part of the picture. It is not an absolutely sure picture for the highbrows or particular audiences, as it is not critic proof. The players "play up to their parts" in the accepted way in many places and the scenes with running horses are really fine. The lesser characters are likable. The photography is good. – The Moving Picture World, May 4, 1918
