First of all, I would like to remind some of the other reviewers that the point of the book is to be a STORY and NOT a scientifically documentation of the future. If you think its a problem that some scientific details are wrong, then perhaps you can name a book where every detail is perfect. If you can do so, then I will agree with what you say. The book was interesting and was accurate enough for me. The next thing you comlain about is how the character only things about adultery and his best friends death. Obviously you don't know what it's like to lose someone, otherwise you would realize that it's a hard thing to get over, and for the adultery bit, well, if you were contemplating cheating on your wife, then I assure you that you to would spen a great deal of time thinking about. So what you to be UNrealistic, is actually what the main character WOULD be thinking. Another complaint is that the plot is a copy of Star Trek. Maybe your right, but this was ten times better than Star Trek, because I hate Star Trek and I love this book. You complain about the Waldahudin, and how they are designed, but do you really think an alien race will be thought provoking and in-depth just because they're aliens? No, it's bull and you know it. Aliens don't follow a schematic, they are the author's creation, and he/she can do whatever he/she wants with them. This was an excellent book, maybe even my favourite of all time, and if Mr. Sawyer ever reads this review, I hope he realizes that SOME people actually appreciate good writing, unlike some morons I can think of.
