Stupidity: When the Pteradons are loose and flying over the crowds, people run from inside buildings out into the open where the birds are attacking people. (01:22:00)
Suggested correction: A person is smart, people are stupid. A crowd in a panic would do exactly that sort of thing. Like trampling over each other running in panic from a shooting or a fire when not needed. It's the nature of panic in humans as a group to act stupid. It's not a movie mistake. It's actually one of the more realistic parts of the film.
Suggested correction: The dinosaurs were also breaking into/attacking people inside, so they weren't safe no matter what.
True, but one option is certainly safer than the other.
Stupidity: The film is set around Christmas time, There is a Christmas song playing in the airport scene and there is a decoration on the family house front door. Surely any amusement park or zoo would be decorated for Christmas and have Christmas souvenirs and stuff. Somehow, after the airport scene, there is no mention of it whatsoever.
