Honestly I get frustrated when people (mostly my extended family admittedly) take from that movie the idea that the message is "dinosaurs are impossible to contain safely and we should never try to somehow recreate one". Like, no, we can make zoos for large, fairly intelligent predators or even bigger herbivores just fine, we do it all the time with things like lions and elephants, dinosaurs arent godzilla or anything. The issue with Jurassic park was that it was run by cheapskates that wanted to get something done fast on a budget without concern for doing it right. It would be like making a movie about the Oceangate disaster and having people conclude the moral of the story was "You shouldnt want to build a submarine because humans arent meant to go down there and it will inevitably go badly" rather than "You should spend the money to build your submarine the right way"
