Query: Disappointing - a poor novel as well as a lost opportunity.

State of Fear was very disappointing. Crichton had some important points to make regarding global warming, and he tries to illustrate them by means of a wild tale of adventure and intrigue, but the novel is so poorly written that it's unlikely that many people will think seriously about the issues that he raises. The character development has the depth of a Superman Comic Book, and the plot line is just about as believable.Having some professional experience in related fields, I happen to share his opinion that the public policy discussions regarding global warming have so far failed to adequately reflect our current state of scientific knowledge. Because of this, I'm particularly saddened that he lost the opportunity to contribute to the debate by producing such a shockingly poor novel.
