I read it for what it was: an fun adventure romp in the Caribbean. Not a bad adventure yarn, but not his best. This book comes across as one he wrote to "loosen up his tie." There's no exhaustive bibliography, or message for/against science, or Earth-shattering revelations. As far as I understand it (Wikipedia) Crichton was working on (or at least thinking about) this book since the 70s. This leads me to believe that he worked on it whenever he found some leisure time to let his hair down and relax a bit. Don't pick up this book expecting anything but action, adventure, debauchery, and lots of violence.
