The stars of the show, the dinos.

The IRex was a great concept, but I felt like it should feature even more.

All of the dinos are Gmodified. Run with that concept.

The IRex is the next wave, but all the predatory dinos have been enhanced for greater intelligence so that they can be trained and controlled. This has the unexpected result of them wanting to hunt to learn to be better predators, like a cat or sea otter playing with it's food, instead of for food.

Also, the IRex would have little military value. Easy target. Lots of small, smart, and quick little dinos, 1 1/2/to 4 ft tall, running around like GREMLINS. They could even want tho train the raptors to hunt the smaller ones as clean-up after battles.

All more expensive. This is the Jurassic franchise. Imax3D. 50 million more for great FX that greatly enhances the story will almost certainly earn back it's money. If ever they are going to swing for the fences....
