Chrichton tends to leave loose ends untied and use the same plot repeatedly, but I enjoyed this book and think it better than most of the best sellers out there, the majority of which I can't stand. Which means most people will not be offended by its literary quality.
I guess I hope the book sells well but I can't tell you how many times I just stopped and said to myself "Wait a minute, people just wouldn't do that" while reading it.
