Michael Crichton's original bestseller "jurassic park" was translated to screen in many ways flawlessly. It introduced characters and thematic elements that stuck with viewers from that day forward and inspired Hollywood to try again and again to recapture that original viewing experience. The movie, however, missed a few plot points entirely and some of them have been recovered in the sequels, but some of them have not.
Survival Horror
"Jurassic World 2" will be darker according to Chris Pratt, who went on to say it would also be funnier. Like the original film survival will be the focus as the scale of the incident will be increased in part by taking action off of Isla Nublar.
Isla Nublar is the site of both "Jurassic Park," and "Jurassic World," respectively. Collin Trevorrow, who isn't directing the sequel but did return to co-write the script with Derek Connolly, says that the film will feature "Weaponized animals." as the tale includes elements of animal abuse and experimentation. Trevorrow and director Steven Spielberg are working on the trilogy which may see the third installment as soon as 2020.
Spoilers
The primary filming location of the film is London. While certain scenes are being filmed in Hawaii Isla Nublar will make only brief appearances in the movie and certainly will not be the primary setting. Multiple agencies within the film will be involved in dinosaur cloning; this raises the possibility of wars between corporations involving dinosaurs a lot more likely and certainly might explain how some characters are dead in some films and alive in others.
The movie is again being referred to as the 5th movie by the director meaning there could be clues in the other movies. Dr.Henry Wu will be returning which is promising news as well.
Conclusion
While it is certainly early to speculate on too many details, there are certain constants in the "Jurassic Park" universe that fans have come to expect.
Provided the director offers enough terrifying elements, which are a must for the series again to capture our imaginations, this installment may be the most thought provoking experience offered by the franchise. After all, how many characters in the sequels were clones? Will the military style dinosaurs stand a chance against medical experiments gone awry? Will the Jeff Goldblum character's clone say "Must go faster?"
