Science fiction writers

The film won the Hugo Award for Best Dramatic Presentation, as voted by science fiction fans and published science-fiction writers. Ray Bradbury praised the film's photography but disliked the banality of most of the dialogue and believed that the audience does not care when Poole dies. Both he and Lester del Rey disliked the film's feeling of sterility and blandness in the human encounters amidst the technological wonders, while both praised the pictorial element of the film. Reporting that "half the audience had left by intermission", Del Rey described the film as dull, confusing, and boring ("the first of the New Wave -Thing movies, with the usual empty symbols"), predicting "t will probably be a box-office disaster, too, and thus set major science-fiction movie making back another ten years".

Samuel R. Delany was impressed by how the film undercuts the audience's normal sense of space and orientation in several ways. Like Bradbury, Delany noticed the banality of the dialogue (he stated that characters say nothing meaningful), but regarded this as a dramatic strength, a prelude to the rebirth at the conclusion of the film.

Without analysing the film in detail, Isaac Asimov spoke well of it in his autobiography and other essays. James P. Hogan liked the film but complained that the ending did not make any sense to him, leading to a bet about whether he could write something better: "I stole Arthur's plot idea shamelessly and produced Inherit the Stars."
