Query: Crichton was not quite "on" this outing

This book is fast-paced and well written, especially the first half, but the plot is not as well constructed as some of his others. The problem is that subsequent events render earlier events illogical and senseless. The book starts out well but reaches a very disappointing resolution, as if Crichton bit off more than he could chew. The fact that this book was made into a movie demonstrates, yet again, that Hollywood will go with a project of dubious merit if it is attached to the name of a proven winner.
