Love the book.
One I read when I was young, 16 or so, and have read a few times since.
I remember the movie scared me some.
I have heard Crichton as writing science books with 2 dimensional characters and this would be one of them. I never realized it till I re-read it but for me it is still a great read. Don't watch the more recent remade movie as it butchered the book.
