I don't write science fiction books, but this was an interesting peek for me from the perspective of the reader, on what things writers (or movies) could be getting really wrong when telling their stories. I'm certainly not an expert in most of the fields there are chapters for in this book, but when I know something is wrong or outlandish in a science fiction story it drives me crazy. I think this could be a great, conversational resource for someone wanting to write science fiction.
