This movie is a mess for sure but I sill like it. I like theme parks, I like dinosaurs. I like dinosaur theme parks.
All your criticisms are valid. But it’s still better than Jurassic Park 3 (apologies to Mr. Johnson. He kept it from being worse).
It’s probably not possible to make a compelling JP sequel, so at least this one compensates by trying to do several things at once and not really getting any of them right.
