This is a science fiction movie with typical British black humor without extensive use of special effects. Although the sci-fi elements in the film are lines, the shock it brings us is no less than that of popcorn movies built with hundreds of millions of dollars.
——"Science Fiction World"
The film does reveal a small-cost method of shooting science fiction films. Perhaps, only the imagination rooted in our hearts is the charm of science fiction films. If they are really shown on the screen, then the attraction of science fiction will disappear.
-"Critics Handbook"
The film very forward-looking uses dialogue and imagination as the framework of science fiction films, which is very meaningful. If you still rely on special effects to make science fiction, it is obviously outdated. Someone made movies like this decades ago. Perhaps this kind of science fiction, which is maintained by dialogue and our imagination, is the real science fiction.
