The 4th film in the Jurassic Park series and the second sequel that Steven Spielberg did not direct starts off well enough with enough call backs to the first film of the series but quickly turns into a monster movie with a run away super killer dinosaur that was spliced by the DNA of other prehistoric creatures for the sake of selling extra tickets. If my description of the plot Is pretty simplistic,it's because the story is that simple. So forget the dangers of science morality tales that both "Jurassic Park" and "The Lost World" gave to it's stories and just accept that the series has become a standard creature feature that just swaps out it's main monster for every new installment. The last film in the series "Jurassic Park 3" pretty much threw away the whole plot lines of the first two films just to give us a chase film with a dinosaur that was never even seen in "The Lost World" and that film was set on the same island. While "Jurassic Park 3" just went on a painful 90 minutes long montage of talking raptors, horrible scenes of family bonding and an visible annoyed Sam Neill looking like he's about to go postal on the people working on the film set, Jurassic World manages to be a hell of a lot more enjoyable experience for the viewer in terms of just trying to inject a sense of plot and continuity to this other wise creature feature.
As a standard creature feature, the movie works well and gives you your money's worth of dinosaurs doing collateral damage to property and personnel with the occasional park visitor being killed for good measure. Throw in your slack jaw good guy ( Chris Pratt) who feels that the creatures are misunderstood and works with good guy dinosaurs(I Kidd you not) to help stop the super killer dinosaur. Throw in an human adversary for our hero to fight with ( Vincent D"Onofrio) who would blow the whole island up to get this monster and add an human element like two lost children who are related to a employee at this crazy theme park who by the way has the hots for our hero and you have the entire story right there.
It's hard enough to keep a franchise going, especially when you're dealing with dinosaurs walking the earth. You will eventually hit a wall in terms of storytelling if your primary goal is to keep turning these films out with out any care what so ever. We saw that with "Jurassic Park 3" where all the plot points from the previous two films were abandon for a B Movie creature feature. "Jurassic World" tries hard to correct that by having the movie be about something a little more and try to connect itself to the first film of the series. And Its much better film for it but it still ends up a creature feature all the same.
