It wasn't until male dinos started showing up that things went to pieces.

A quick reminder that Hammond actually does make a comment that he should be the one going with Muldoon to restore power, because she is a woman, and she just rolls her eyes at him, and tells him they'll talk about "sexism in survival situations" when she gets back. Hammond isn't demonized for it either. The film treats him as a man of integrity who just has some old-fashioned ideas.

In the book the boy was older and the hacker the girl was younger and generally useless. They just reversed it for the movie. Pretty much everything the children do that was beneficial in the movie was done by the boy in the book.
