Jurassic World is a lot more like Japanese Godzilla than Jurassic Park, which is strange.
What do I mean by this? Well, in old Japanese Godzilla films, Godzilla usually came to Tokyo, stomped around a bit. Humans ran screaming. Godzilla's enemy of the week came stomping around, more humans ran screaming. And then the two usually fought each other cause humans were useless in the film.
Jurassic World is a LOT like this. It's both a disaster film; but with dinosaurs, and a godzilla film in the sense that nothing humans do in the film really matters as the film ends with a dino-on-dino brawl that ends up with the big bad dino being killed.
Quick summary of the film, Jurassic World creates a new super-dinosaur to attract people to its theme park but it's basically too intelligent and escapes from its cage and goes on a rampage through the island, only to be stopped by the tag-team match-up of a T-Rex, a Velociraptor and a Mosasaurus.
The humans as a whole are useless in the film; except for Owen Grady who actually seems like the smartest person in the film at times, and the more relevant thing they do in the film is release the Trex and direct him to the super dinosaur.
The film itself was decent though. I wouldn't say spectacular because it really did nothing that was outstanding but I would say it was very well put together. The few criticisms I have with the film mostly deal with how the super-dinosaur is too super (or the humans in the film too stupid) really but the genre of the film kind of demands that the super dino have plot armor until the climax. It wouldn't do for the superdino to die midway in the film just because humans have a damn rocket launcher and shoot it (They actually do and they missed while it was standing still).
Overall, it was a decent use of 2 hours and the dinosaur fight at the end was entertaining; although I maintain that the Trex should have died once he got his neck chewed on by the super dino who was able to crack an Ankylosauruss head.
