This book certainly kept me turning the pages, but it definitely doesn't have that ol' Crichton feelin'. The "science" in this science fiction was weak and unbelieveable. Richard Preston was able to keep the basic formula of "bad company lures team of innocents into dangerous new world; bad company is brought down by own technology", but the story was about as shallow as that formula. It's a great, quick read and it will gross you out with lovely details of nature's harshness, but Crichton fans will long for the days of Lost World.
