Honestly I prefer Hammond as a well meaning grandpa.

Hammond in the film is kinda a stand-in for Spielberg himself, the entire flea circus monologue is Spielberg lamenting about his role in the entertainment industry and whether he did more harm than good in it.

To me it just reinforces that the problems with Jurassic Park were systemic. It was doomed to fail no matter how well meaning the creator. The problem isn’t the individuals, it’s capitalism.
