I didn't see the last Jurassic World film but I did play the Lego game of it, so I was familiar with the backstory to this one. In this one those that survived the theme park accident of the other film are encouraged to go back to help get some dinos off the island before a volcano kills them all.
It's alright. It's one of those films where you have to disbelieve a little bit, not just because it's about dinosaurs but because some of the story is really dumb. It is a good romp!
