Why are there no good dinosaur films?

Until we get a movie about dinosaurs and not people who happen to be in a place with dinosaurs, it will always be like that. Of course studios are not risking money for a film that’s 80% dinos and 20% people.

Have you seen the TV show Primeval?

Like so many shows, it kinda petered out once they were cancelled, but it is still worth a watch. https://www.cbr.com/forgotten-sci-fi-dinosaur-series-perfect-for-jurassic-park-fans/
