the cg doesnt look that good, even by todays standards
I imagine they couldn't get a license to sell genetically modified animals as pets in any country and had to keep all the dinosaurs confined to Isla Nublar. There's probably a baby sauropod petting zoo for the kids, but huge vicious murder machines are always more interesting to the public. And every time the public interest wanes they have to one up their previous animal to attract new guests.because if it was a reboot, ok, I'd just barely buy the premise of them creating a new kind of dino just because they could.
however, I still wouldn't be able to buy that they'd create a murder machine for their family theme park, instead of, lets say, pocket sized, dull-clawed pet dinos.
