Dinosaurs shouldn't be villains or hero's in these movies. They should be attempting to act out their natural role in the food chain / ecosystem. The intrigue should be in the dinosaurs having been taken out of their natural environment and placed in an artificial one.
The movies need interesting human characters. The antagonist should be human not a Dino, to stop them turning into a slasher movie.
The movies also should be cerebral to an extent with strong themes that are explored e.g. JP looked at God versus nature, control versus chaos, gender stereotypes in survival situations and fatherhood. TLW further explored the idea of nature versus consumerism, are clones entitled to rights or are they a commodity, parenting (the dinos and Ian) and PTSD (Ian again) and Speilberg got to do his King Kong bit. JP3 explored what happens if you shoot a movie with an unfinished script, it was a pioneer in subverting expectations in a bad way (probably inspired Ryan Johnson) and taught young Bravomite an important lesson that third movies always suck (except return of the king).
I have faith in Gareth Edwards as a visual storyteller, just hope the script is good. It is positive that David Koepp is back as he was involved in both JP and TLW.
