OK, I went to Jurassic World.
I understand why some paleontologists despise it - it wouldn't have hurt the movie to make the dinosaurs more in line with the latest scientific discoveries, and they should have taken the opportunity to make the dinos more accurate (which also would make them more visually interesting). In fact, the raptors are LESS accurate than in the last movie, and it's disappointing. (And, why, in the name of Roy Chapman Andrews, do we keep seeing them with cute little "bunny hands"?) And how can pterosaurs lift way more than their own weight? And why does the mosasaur look different sized in every shot, and why is it bigger than a blue whale to start with? And so on...
Nevertheless, this is a terrifically enjoyable monster movie, with the right balance of scary and funny moments. One death is drawn-out and gratuitous, but the rest of the violence is ok. The actors generally give good performances in the usual monster-movie stereotype roles. There are enjoyable nods to the original Jurassic Park, and there's a climax where my all-time favorite dinosaur gets on the screen again. The last joke, played out as people evacuate the control room, is a hilarious skewering of a common movie trope: I won't spoil it for you. There was a lot of predictability in the script, but the filmmakers did a decent job of hiding it. (You knew the sinister defense guy was going to die, but they made you wait for it.) And most of the ideas about what would actually be in a theme park of this sort, and how it would be marketed and run, seem pretty spot-on.
(Missed opportunity: a TV network should have had the older Ian Malcolm commenting on why you didn't need chaos theory to predict that a plan that twice ended in disaster was going to end, once again, in disaster. "They've removed the chaos. It's back to old-fashioned linear mathematical certainty.")
No, I don't believe in the super-powered Indominus rex. You don't get significant additive (that is, positive or enhancing) characteristics of another species as a random side effect of splicing in some genes for some other reason. That we MIGHT be able to someday design something like this - and I think we might - is a scary thought, though, and it works great in the movie. And the discussion over the creature's name is funny and entirely plausible.
The CGI (save for a couple of moments) is good, and if the mosasaur is insanely big and some of the dinosaur behavior makes no sense, well, I'm willing to forgive the filmmakers most of their faults, because they created great entertainment. Turn off your brain, grab your popcorn, and enjoy the action.
