I get that angle, I understand it. But how it then doesn't work is the stupid lax security angle on the whole thing again. Fine, sure, make a super-dinosaur. But keep it somewhere with a fucking laser ceiling or some shit, with concrete over the top too as a secondary. Jurassic Park happened, where the electric fences failed and they chewed on through.
The follow up isn't "oh, well we built like some wooden wall high up and... oh it climbed it huh?" Thats just when an entire cinema audience is making "DUH-DOY?!" noises and getting frustrated. Even more with whatever system they have to stop a giant boat sized alligator in a specific body of water and not swim on out to fuck a tugboat in Jamaica or whatever for hijinx.
All this in a world where the military has had to step in multiple times to deal "with this dinosaur bullshit again".
