Technically, the movie is not completely revolved around dinosaurs, according to Wikipedia, the storyline consists of "Mills and Koa must make their way across an unknown terrain riddled with dangerous prehistoric creatures". In other words, the planet is similar to "Skull Island" in King Kong (2005).

Jurassic Park/Jurassic World media franchise is known for being a king of Dino movies. Until the last 2 installments (Fallen Kingdom and Dominion) which are the worst movies of the whole series. It is obvious the market requires a competitor, and I hope "65" will be the one.
