The dinosaurs are bigger, the rides are scarier and there's a dashing new leading pair as the main attraction: Jurassic World is open for business again and hoping to entice a new generation used to getting more bang for its movie buck.

The film, out in US theaters on Friday, revives the classic sci-fi action franchise that began with Steven Spielberg making dinosaurs come to life in 1993's Jurassic Park.

But two decades on, as Bryce Dallas Howard's Claire slyly says in the film, no one is excited about seeing a dinosaur anymore. Yawn.
