Jurassic Park 4 is a doomed concept, I'm certain of that. It has all the traits of films that bombed and sucked. They don't have an inspired idea for a story, but they want another film. This kind of motivation has never resulted in a good film. I have read so much about shitty story ideas. Like some madman trying to combine human and dinosaur DNA. Another story was about someone using dinosaurs as distraction for a bank robbery. Now it's something like "Dinosaurs all over the world!" but what story is that?
I wanna benefit the doubt, but gotta admit your thinking is entirely sound. Can we get a faithful adaptation of Doyle's The Lost World
