According to the director, the new Dinosaur is developed because the visitors got bored of the same old Dinosaurs so they developed a new hybrid creature.
That's a strange reasoning. One, they're dinosaurs. I don't think the intrigue would fade that quickly, if ever. And two, zoos seem to do alright without having to genetically engineer crazy new animals. If baby pandas can keep interest high, extinct dinos should have even less trouble with that.
Humans get bored of the newest thing so quickly. Even themeparks and zoos suffer from this. What was hot two years ago, isn't anymore. So yeah, I'm betting that after a few years, people will get less excited about dinosaurs.
And even if they didn't, marketers are always thinking of the next big thing to keep people psyched about their merchandise.
I mean, even in the original novel, Michael Chrichton already brought up this point, when Wu tried to sell the idea of genetically altering the dinosaurs, going to a new version of the DNA, to make them slower and appear stupid, because that's the general idea people still had of dinosaurs in the late 80's. So why not give them what they want, instead of what's real?
This movie actually works with a plot point Chrichton himself already thought of 25 years ago.... No matter how great you think what you're selling is, people will get bored with it, so make sure you've got something new and improved in the background.
