Jurassic Park 3’s Connection To The Original
The connection to the original for JP3 is a little slippery. Dr. Alan Grant is interested in a raptor’s larynx and wants to do more research, and only goes along for the ride because he’s been tricked.
Dr. Grant even says himself that he knows nothing about this island since the first island he was on was Isla Nublar, not Isla Sorna, so he doesn’t even know where he is.
The Connection To The First Movie’s Victor: The Lost World
As I mentioned earlier, both films feel unnecessary, but at least The Lost World feels like it is a natural progression to the story, while JP3 almost feels like fanfiction. It’s the best sort of fanfiction, sure, but fan fic nonetheless.
