The Jurassic Park franchise has wowed audiences for decades and showed the wonder and terror that can come from tampering with genetic power. But more than anything, the characters and dinosaurs have pulled audiences in. This was best shown in the original Jurassic Park with its leads, Dr. Grant, Dr. Malcolm and Dr. Sattler, who have all returned, in some capacity, in future installments. But unlike the others, none have ever been as unlucky as Dr. Grant, who spent most of his time as a paleontologist, running from the living versions of the creatures he studied.
