I've long found the notion that the lesson of Jurassic Park, if a fictional story like that must be taken to have one, should be something like "science/genetic engineering is bad" or "you can't control nature" to be a bit silly, given that, well, it's a zoo. With pretty big animals, to be sure, but dinosaurs were animals still, not kaiju or dragons or whatever other fantasy monster, and some genetically modified to be somewhat bigger and lack feathers would still be such. It's a story about some people building a zoo badly because they didn't do their due diligence about the animals they had and cheaped out on staff and the systems they had for containing the animals, and somehow people get the take away that "these animals are special and can't be safely contained" rather than "letting rich people cheap out on safety is a bad idea".

Were one to write a broadly similar story where someone cheaps out on a park containing elephants and tigers, and they get out and maul some people, it'd be obvious, but give the tigers scales and make them born in a lab and suddenly it's a monster movie.
