Critical views of the film in the years since its release generally consider it to be one of the lesser films in the Hammer and Nigel Kneale canon. Critic Bill Warren finds its to be "an intelligent but commonplace adventure thriller with the Yeti little more than background figures… a little too ponderous and hence unexciting". Similarly, John Baxter felt that "in recreating a peak in the Himalayas, the set designer had more control over the film than the director, and despite some tense action the story drags". Baxter acknowledged however that the film exercises "a certain eerie influence", a view echoed by Hammer historians Marcus Hearn and Alan Barnes that "the film conveys a taut, paranoid atmosphere; set largely in wide open spaces, it's remarkably claustrophobic in scale". Nigel Kneale's biographer, Andy Murray, finds the film "eerie and effective" and also suggests the scenes of the expedition members calling out to their lost colleagues across the wastelands influenced similar scenes in "The Blair Witch Project" (1999).
