Spoiler:
I just don't get why the girl released the dinosaurs at the end. She said that they were alive like her but so are the hordes of people that the dinosaurs will kill...and maybe she'll get killed by a dinosaur eventually. I also don't get why they wanted to save the dinosaurs in the first place, talking about they're going to die this, they're going to die that. Like okay, but everything dies eventually, why do you want to save some dinosaurs that want to eat you? It's like asking a gazelle to save a lion.
Overall, the effects were good but the story line, not so much.
