In terms of beloved science fiction movies, it's hard to find one more roundly beloved than "Jurassic Park." Directed by the legendary Steven Spielberg, every dinosaur movie that has come since has had to live in its shadow, which is probably why there are so few studio-produced dinosaur movies outside of this franchise. Spielberg's "Jurassic Park" was a box office smash that changed movies forever. You didn't like "Jurassic Park." Indeed it does, and that thing is "Primitive War," the greatest non-"Jurassic Park" dinosaur movie ever made.
