Moria likes it, and says it " is one of the most neglected and underrated of the classics from England’s Hammer Films." 1000 Misspent Hours calls it "An extremely bizarre offering". StompTokyo says,
there's something about the obvious culture and confident earnestness of these two actors that makes their films downright irresistible. Lines of dialogue that would be laughable in the mouths of lesser men sound natural when handled by these distinguished-looking gents. The studio, recognizing the good thing in its grasp, pumped Cushing and Lee for dozens of films, and the history of cinema is richer for it.
