I have to disagree the theme of dinosaurs in the real world is wildly unrealistic and stupid.
It's entirely a question of what dinosaurs you choose to focus on and how. Obviously, wild T. Rexes aren't going to be snacking on random commuters and disappearing into the woods. But there's a lot of potential story in the smaller, harder to eradicate dinosaurs like Compys or Dilophosaurs. Especially if you explore the tension in poorer places that can't afford every possible precaution and constant fast reaction forces for any dinosaur that shows up, meanwhile the rich communities live in dinosaur proof gated communities and build giant border walls to keep the dinos from spreading to their area. Then add in the tensions around dinosaur rights - the big, easy to like ones that don't actually hunt people could easily have become protected species in some places, but that wouldn't stop them from coming into conflict with locals, especially poor locals who have to compete with them for food, anyway.
Then there's the constant stream of completely unpredictable random outbreaks from the black market trade because there will always be people getting their hands on dinosaurs illegally (as eggs, or - even harder to track - genetic material) who aren't at all equipped to keep them under control long-term, whether it's illegal roadside zoos, illegal research labs or just rich morons who want a T-Rex for a pet. You can stop each individual outbreak in a matter of hours if you're willing to put enough resources into it, but you're never going to put the genie back in the bottle enough to stop the outbreaks from happening at all.
Then there's the ones that wouldn't seek out civilization enough to cause major trouble, but would still be seriously dangerous for anyone unlucky enough to find them (Raptors probably make a lot of sense here, though the recent movies were being weird trying to put them in the Rocky Mountains instead of in a jungle region). Those kind could even be beyond any kind of govt. intervention if the local govts. found it more convenient to deny they exist than actually try to do something about them.
And, of course, there's the ocean-going (not technically) dinosaurs. Mosasarus would likely be terrorizing fishing and sailing communities for a long time before anyone managed to understand it's behavior patterns well enough to predict where it would go next and be ready to capture or kill it. The ocean is way too vast to succesfully and easily track it unless you get super-lucky.
And after all that, there's still the genetic engineering angle, as well. Any species that included the I-Rex style camouflage genes would be completely untraceable.
A movie that genuinely wants to explore the idea of humanity actually having to coexist with dinosaurs could be absolutely fantastic if well-made, as well as way more realistic and believable than any of the JW movies we actually got. And it's really the only place the Jurassic franchise has left to go that isn't just warmed over pastiches of all the franchise entries that already exist.
It's really a shame they keep tossing all that potential out the window for endless generic mad science bs.
