Not an extinct franchise by a long chalk

When Jurassic Park came out in 1993, my mum was proud to boast that I was into dinosaurs well before it became fashionable.  And, contrary to what the hubristic characters say in Jurassic World, dinosaurs still are fashionable.  Why else would Hollywood return to the well when a serviceable trilogy already exists, given the safety-first nature of studio execs that stymies many an original idea (had Star Wars Episode IV been pitched today, it may never have got made).  Jurassic World has fulfilled all of the execs' expectations becoming the third most successful film at the box office of all time or somesuch (in the future) surpassable figure.  Towards the end of the picture, the ground is laid for another installment to take off like a pterodactyl.
As Alexander Walker used to do in his Evening Standard column in the interests of entertaining those who will not go to the cinema, I will dissect the film from start to end.  Jurassic World (even though most of the creatures habituate from the Cretaceous period) is standard Towering Inferno-style, man in trouble through man over-reaching and this particular Tower of Babel is a fully functional park attracting tens of thousands of visitors.  The trouble is that its operating costs continue to exceed its revenue and so the geneticist boffins must go for bigger, better. 'cooler' dinosaurs which never existed in the first place to attract the corporate sponsorship, hence the Indomnis Rex, a hybrid between a Tyrannosaurus Rex and a Velociraptor and some other animals that allow it to mask its heat and camouflage itself.  This time, unlike in the first film where the park was undone by human venality, here the park's steady collapse comes from the Indomnis tricking its human captors into entering the cage after they think it has escaped and then some slob of a guard opening the main gate to escape (his life expectancy is only enhanced by a couple of minutes) allowing the Indomnis to break free.  Thereafter it goes on the rampage, repelling all humans efforts to subdue it (this leads to a moment of great pathos when slain diplodoci litter the verdant landscape).
There are some awesome action scenes in Jurassic World, one of my favourite being a battle between the Indomnis and an ankylosaurus.  The attack by the pteranodons and other flying lizards on the tourists has a brilliant touch of air raid sirens whirring up.  Another delicious touch, given Steven Spielberg's helming of Jurassic Park and Jaws, is the great white shark, the ultimate predator in the latter flick, being fed to a mesosaur here.  The dinosaur's claws which subsequently turn out to be the talons of a bird is a nice nod to the prevailing theory of surviving dinosaurs becoming our current avian friends.
Chris Pratt is a likeable hero, continuing his turn from Guardians of the Galaxy (naturally he should be at home here after his TV role in Parks and Recreation).  Bryce Dallas Howard is a tolerable heroine, even if she does wear heels in all situations, including being chased by a tyrannosaurus rex (Pratt's character openly mocks this).  Apart from a few douchebag moments from the teenager, the two kids are far better than the scweaming pair from Jurassic Park.  There is a harassed British nanny (posh totty rather than Mary Poppins) here who may or may not have been eaten (it's not entirely clear).  Plus there is a role for the pimply, high-pitched dogsbody from The Simpsons, in human form, as the bubble car attendant - "I just work here."
The bad guys in Jurassic Park, the raptors, here are the good guys, have a change of heart to become bad, before re-evaluating their life choices and going good again.  It's very clever on a meta-level.  The real villains, Indomnis and some humans, get richly deserved evisceration.  The playboy owner, building on the legacy of Richard Attenborough's Hammond from Jurassic Park, isn't a bad person as such, but from the moment he gets into the helicopter to hunt the Indomnis, you know he's a goner and in some ways that brings it closer to the book Jurassic Park, rather than the film that was named after it.  The original park is explored and the banner that fell at the conclusion of the first movie "When dinosaurs ruled the world" is here wrapped up and burnt as a lamp round a raptor wishbone.
There are flaws. The sound quality isn't tip-top throughout and given the din multiplexes can cook up that isn't good enough, trying to glean from subsequent sentences or actions what was said.  At one point Pratt quips, "I was in the Navy, not the Nhuhuhuh."  It took me about 30 seconds to what out he meant Navajo which is smart but undermined through having to decipher it.  Some people laughed and even they have pitch-perfect hearing or are canned laughter audience regulars, guffawing at cues rather than jokes.  The Indomnis, like many a bad dinosaur B-movie, seems impervious to high-calibre bullets and a bazooka only slows it down - that's just silly.  The pteranodon attack doesn't have the courage of its convictions as only adults are attacked when surely the flying monsters would have gone after the bitesize children for snacks.  The conclusion is exceptionally lame as well, the tyrannosaurus and the raptor eyeing each other and, unlike in Jurassic Park where they savaged each other, here going their separate ways after fighting as allies.  Then we get the final cookie-cutter insult - dozens of people must die, as in Jurassic Park III (and billions in 2012), to facilitate the reunion of a divorcing (or divorced) couple and make the kids happy.  Very dubious morality.
So leave the moment the Indomnis gets its just desserts.  It's a blast for the rest of the time. 3.5 out of 5.
