The first major trailer for Jurassic World: Fallen Kingdom has just arrived and even by contemporary standards, it does give a great deal of the film’s plot away. It’s also not coy about showing off the latest dinosaurs that feature in the movie. Overall, as a trailer it certainly does its job and whet’s the audiences appetite. I am certainly interested in seeing this blockbuster next summer. But as ever with anything that happens online, there has been a degree of push back from those who feel that it shows too much and that it should have come with spoiler warnings. Some are arguing that this culture of “showing the best bits” is a recent phenomenon but a cursory review of classic movie trailers on You Tube, will show you that this has always happened.
