Same here Maverick. I've read this along with most other Michael Crichton books. This is a great one, the rest are very well done as well.
Getting started on Dean Koontz and Robin Cook now...
there have been a few Crichton books I regret were made after Jurassic.... Congo could have been a great movie if done right, but something tells me it can't be ever.
Sphere, well what can I say. the cast with the exception on Sharon Stone was quite good, but so many plot elements were left out, and it was just butchered by whoever did the screenplay.
