The Western Review says it "has aged gracefully in its treatment of race relations where so many of its contemporaries appear (their other merits aside) offensively grizzled." Variety calls it "an appealing, sentimental Indian romance, with plenty of action." The New York Times has a review from 1950 that says, "one might wonder from this exhibit ... whether it isn't the white man, not the Indian, who should be regarded as "good" only when he is dead." TCM and MSN have overviews.
