Volcanoes Just Don't Work Like That
Jurassic World: Fallen Kingdom is like no other volcano movie ever made. On the one hand, the visuals are absolutely perfect. This is a volcano that has been dormant for an unknown amount of time, but has finally rumbled to life; the longer the period of dormancy, the more explosive the eruption when the volcano erupts. And make no mistake, this is an explosive eruption - when the volcano clears its throat, you get a scattering of volcanic bombs. Then, pyroclastic flows sweep down the slopes of the mountain, as in the image above. Visually, this film couldn't be more scientifically accurate.
Unfortunately, the script isn't quite as accurate as the visuals. Take that stunning pyroclastic flow as the classic example; a pyroclastic flow is a swirling cloud of gas and ash, and can travel at up to 700 km/h - and yet Owen comes close to outrunning it. When the pyroclastic flow eventually catches up with him, he's briefly obscured by it - and yet manages to dive into the water. The problem is that a pyroclastic flow's temperature is in excess of 1,800 degrees Farenheit. The skin should have been seared from his bones. Not to mention, a moment's exposure to that should have led to asphyxiation, as scalding hot toxic gases burned his lungs.
Locked In - But With Another Way Out
Now let's look at another problematic scene during that whole "volcanic eruption" part of the film's plot. Mills's agents trap Claire and Franklin in one of the old Park bases on Isla Nublar, and they spend quite a bit of time trying to work out how to exit... Until a lava flow drives a carnivorous dinosaur into the building. That's when they suddenly notice an escape hatch in the roof. So why didn't they just climb the ladder and exit that way in the first place?
The Human Cloning Problem
The biggest twist in Jurassic World: Fallen Kingdom is nothing to do with the dinosaurs at all. Rather, we learn that Lockwood perfected human cloning, and that his "granddaughter" Maisie is actually a clone. It seems this is why we've never heard of Lockwood before; he and John Hammond parted ways years ago, disagreeing over the idea of human cloning. Hammond was fine with creating dinosaurs, but trying to reverse death?
It's a smart retcon, and at first glance it makes a measure of sense. Unfortunately, though, it doesn't hold up to scrutiny. Jurassic World established that, in-universe, John Hammond died in 1997 - 20 years ago. That means the disagreement between Hammond and Lockwood happened even further back than that, but Maisie most definitely isn't 20 years old.
At least there's a potential explanation for this one. Presumably Lockwood came up with the idea of human cloning back when Hammond was still alive, but it took him years to perfect the technology.
The Ending Just Doesn't Work
And that brings us to the final plot hole: the film's entire end montage. The liberation of the captive dinosaurs is clearly intended to be the beginning of a sort of "Dinopocalypse," with man now having to share the world with dinosaurs. Unfortunately, the script just doesn't support that. Eli Mills only managed to rescue 11 different species, and some of them - the Ankylosaurus, the Tyrannosaurus Rex, and even poor Blue - are the last of their kind. We don't know how many individual animals were taken, but they were all carried on a single ship. There were so few of the creatures, that they could all be held in pens in the basement of the Lockwood Estate. There are 27 security feeds monitoring those cages - presumably meaning there are only 27 cages in the first place. You're probably talking not more than 40 or 50 dinosaurs escaping into the wild, and many of them would be unable to reproduce (except through cloning) because they're the last of their kind.
Making this even more awkward, Jurassic World: Fallen Kingdom already revealed that every single dinosaur in the Park had a tracker implanted within its skin. All the authorities need to do in order to round up these creatures is capture one of them, and identify the frequency those trackers are operating at. Those roaming dinosaurs will no doubt cause a lot of problems in the short term, but we're a long way away from creating the promised "Jurassic World."
