I found the movie somewhat boring and disappointing. It was a case of more of the same, and was a missed opportunity to do something a bit different with the franchise.
The trailer gave too much away, in the sense that the movie didn't expand on what we saw in the trailer.
For example, in the trailer we see a brief shot of guests in kayaks. I thought that would be an interesting scene, when things go wrong and they're paddling for their lives. The problem is that scene from the trailer, which is a few seconds long, is all we see. There's no more to it. Several other scenes in the trailer are the same.
I feel they didn't take advantage of the fact that there is finally a fully realized Jurassic theme park. Why don't we see the T-Rex chasing down guests in a monorail? Why don't we see the jeep full of guests trying to escape a dinosaur? Instead of using the theme park, most of the action takes place in the forest, and just feels like more of the same from the first movies. Only the Pterodactyl attack took advantage of the setting.
Even the gyro-sphere scene doesn't feel much different than the jeep attack in the first movie. It was also absurd that the gyro-sphere could be controlled by guests. That would be like letting a guest drive the Kilimanjaro Safari vehicle wherever they pleased. I also noticed that the ride vehicle dispatched before the kids did up their safety belts. That alone might have been less realistic than cloned dinosaurs
