In my opinion, Asimov is brilliant and clearly showed how to cope with difficulties, challenges, I’d say it’s at the stage or degree of selfishness, and pride. As well transferred the emotions of the hero, fear, more fear or stress, because the main character is not accustomed to what he must face. I think that the book deserves a high score.
It’s always interesting when something is turned on its head. The author makes it clear that the man knows his business, always must be able to handle any standing in his way will, in whatever became. Despite the complexity and sophistication of the obstacles.
