In the middle of a Jurassic Park rewatch... No, just no, Lex deserved to die. I know scared kids can act irrationally, but Lex goes against any survival instinct. Even the girl in Fallen Kingdom comes as more reasonable. I mean, burrowing under the bedsheats won't save you from an angry Dino, but running and hiding are the right instinctual responses when faced with a big predator, not going out of the way to broadcast your presence to it.
Really both Genaro and Malcom would have been unharmed if she didn't have the selfpreservation instinct of a hamster.
