Really, I'm going to pull out and use the remake card, something that I'm not prone to want to use. I think a remake of the first movie is called for, possibly something darker and more in tone with the book. As much of a Spielbergian classic the original movie is it's, well, filled with that Spielberg shmaltzy kiddy/familyness to it.
Remake the first book with the darker tones present in it. I suppose also along those lines making the dinosaurs better match up with present-day beliefs on them.
