One of Hal Clement’s weaknesses in these two books is that he likes his characters too much. He wants them to be good people, and he wants good things to happen to them, so the potential backstabbing and betrayals that would add tension are always defused in a few paragraphs.
Writing a science fiction story is fun, not work. […] The fun, and the material for this article, lies in treating the whole thing as a game. I’ve been playing the game since I was a child, so the rules must be quite simple. They are; for the reader of a science-fiction story, they consist of finding as many as possible of the author’s statements or implications which conflict with the facts as science currently understands them. For the author, the rule is to make as few such slips as he possibly can.
