Resourceful kids, even when on their own, can surmount obstacles and survive. Earth has been host to many miraculous and awe-inspiring creatures.
A dark mist envelops a number of airplanes and the isolated island amid roaring thunder and lightning; plane passengers, including young Lucas, plummet to Earth in the dense clouds. Ferocious CGI (computer-generated imagery) dinosaurs gnash their giant teeth, threaten, chase, and surround the two heroes in numerous scenes. An assortment of other imaginary creatures (a giant centipede, man-eating plants) attack as well. A tribe of young black tribesmen (mostly kids; often laughing) chase, capture, and imprison Lucas and Kate. A friendly pet dinosaur appears to be dead but revives after a short time.
