From the minute to movie starts, the green screen is apparent behind the leaves blowing in the wind lightly beside the crash site. The earth is spinning, yet the fire balls are all coming from the same direction at all times of the day. They picked an English speaking girl to act like she did not speak English, and told her to make words up and stuff, instead of actually picking a girl who could not speak English. The sore he receives from the crash Migrates from his left side, to his right side, to his left side, to his right side, and again back to his right side. His acting aside, which I can't stand, there were a couple of good points, which sadly do not deal with the story at all: 1, the terrible giants featured and done so with raptors, which are their most accurate size as we know, the size of a turkey, not the side of a human, and the others are monitor or komodo ancestors, not the commonly featured terror lizards, and when one hides on the bushes, they did a good job with that.
I expected to see Will smith in the credits as the "Earth 2.0" story, but, Earth was better that this movie, by a lot.
Overall, not worth the theatre experience, even if you like Dinosaurs: limited story, bad acting, bad effects (even though the few dinosaurs they did show were actually very well done, texturewise).
