I saw Mad Max and Jurassic World within a 24 hour period of each other. If you can only see one, Mad Max is definitely the way to go. Jurassic World is fun, entertaining, but it's not a smart movie. I mean, the guy is "controlling" velociraptors for God's sake. Everyone laughed when this happened in JP3, why not now? And I have a theory about this movie, and it's not really a spoiler, but avoid the next part if you want to know nothing about the movie:
One of the first things you see is a large dinosaur eating a large shark, possibly a jab at Jaws. Then you mock the dinosaurs that were terrifying in the first JP, the raptors and T-Rex, openly saying that people are bored by them these days. It seems to be an allegory for monsters in the entertainment industry. Poor Spielberg, amirite?
