I agree with DreamMaster.
I hate to say it, but the leaked premise(s) are terrible. How could the park be up and running? The first film ended with the rex demolishing the visitor's center and the raptors running free. More importantly, why? Why would someone invest billions of dollars to capture the animals, pay off the lawsuits, rebuild the park, hire new staff, and then pay insurance premiums atop of all of it?
Then, they would have to explain how they restocked the park. The facility on Sorna was destroyed, presumably with the equipment in facility on Nublar.
The more I think about the film, the more I realize how near impossible it is to create an original, viable story. Hell, a sequel to Westworld would be easier to pull off than this film.
