Political space tales aren't really my thing, but I must say that, politics aside, I was astonished that Asimov was so young when he wrote this. Few writers can write such good prose before middle-age. The story itself is rather mundane for a true sci-fi enthusiast. You'll not find any great discoveries by astronaut explorers or the like, but what it does do, it does well. His treatment of religion is silly though, and like most atheist writers, it's not very well thought out. I've not read anything else by him, but one hopes his later novels were better developed in that area. The mystical hints that run through nearly all of Arthur C Clarke's stories are the most intriguing thing about them. Asimov would have done well to have studied them.
Positive
