Little to do with the science/paleontology (bitching at JP's paleontology feels moot after all these years) and more head-scratching writing decisions that reek of an inability to properly structure a story stuff like>Why the fuck are they trying to weaponize these things when dogs do everything they can but safer and more affordable>Why the fuck didn't they gun Indo down when the raptor pack found her>How the fuck did you manage to miss her with a fucking M134 minigun>How the fuck did you outrun rexy in those cheap heels>Why the fuck aren't you running to the boats instead of hiding from Indo in the shops>Why the fuck is rexy sparing Blue when we've seen her kill (and presumably eat) two raptors in the first film? Especially now that she's emaciated and has had her potential meal in the form in Indo denied her by the Mosasaur?>Why the fuck are these characters so bland and forgettable? I only remember Chris Pratt because he's Chris Pratt and even his character is a cutout.
And so on and so on.
Also the effects for the final fight felt like Rexy and Indo and Blue were made out of rubber. They have no momentum and their movements are so artificial. None of them move believably..
