 Algis Budrys found "The Sentinel" to be infuriating, saying that "one can raise a formidable reputation for profundity by repeating, over and over again, that the universe is wide and man is very small ... while our instruments show that the universe is wide, they are our instruments and we managed somehow to build them.There is no evidence whatsoever that Man is that goddamned small".The story was adapted and expanded upon in the 1968 film, "", made by filmmaker Stanley Kubrick.
