As for the plot, for some unexplained reason, Mr. Neill is lured into landing on Isla Sorna (Latin for "Danger--dinosaurs here!"), where he learns that the millionaire financiers who have paid for the tour have duped him. Only this time there are newer, more ferocious and more intelligent dinosaurs that have been genetically enhanced by evil corporate lab techs to provide the action.
The main intellectual thrust of this movie--and it has occurred to me that "intellectual" was not what Spielberg was going for in the first two movies given the violence and gore in those, so I'm not expecting too much from this one--is to scorn scientists who mess with DNA.
Lost World had more action and is scarier than Jurassic Park. And III has more than Lost World. It has to be this way.
If it weren't, nobody would come. People demand escalating action in movies, especially in sequels.
It is all we seem to care about. If they made Gone With The Wind now, Atlanta wouldn't just be burning, it would be a post-nuclear wasteland, and Vivien Leigh and Clark Gable its horribly disfigured victims.
If they filmed The Ten Commandments the Egyptians wouldn't have drowned in the Red Sea, they would be cut in half by machine-gun fire from Charlton Heston's M-16, which, coincidentally, Heston has been lobbying for since he became president of the NRA. And Kim Cattrall would hang on Heston's elbow--her robe would be in shreds.
Don't even get me started on Hello Dolly.
Sequels have made the whole action trend worse.
Apparently Hollywood honchos think if you have a successful movie, all you have to do is give it a stupid new name featuring a roman numeral, like Gladiator IV: The Lion Becomes King and people will pay to see it again. What do they take us for, morons?
Can there be a worse idea than Jurassic Park III? Hmmm. How about this:
"The list they never thought would come out. It did. Schindler's List II: The Other List"
I fear we will always have sequels. And I cringe at what is coming: ReallyReallyGoodFellas. GoodFellas III: GreatFellas. Gladiator II: The Roman Empire Strikes Back. Gladiator III: This Time It's Personal. Another Perfect Storm. Pearl Harbor IV: China Attacks!. Crouching Tiger, Hidden Dragon: The Early Years.
