Combining state-of-the-art computer character animation with digitally enhanced live-action background, moviegoers are transported back to prehistoric times. Through a series of mishaps, a dinosaur egg ends up on an island inhabited by no dinosaurs, but plenty of monkeys. The monkeys raise the dinosaur, Aladar (D.B. Sweeney), as one of their own. When a meteor shower destroys their island, Aladar and his family of
monkeys escape, ending up back on the island of the dinosaurs that he came from.
They find the island dry and desolate and all the dinosaurs on the move. They are moving together as a herd to the nesting ground, a place they hope is still green and full of life. The herd is led by the mean Kron (Samuel E. Wright), a dinosaur who believes that survival of the fittest is the only way, at the cost of losing members of his herd. Aladar has compassion for the weak dinosaurs and befriends them, trying to help them along.
Kron has no patience for Aladar and his slow friends. Little does he know that they are the very ones who will save the herd in the end. They get so far behind that they end up going a different way and find the nesting ground first. They lead the rest of the herd to it, and it is exactly the paradise they hoped for.
“Dinosaur” gets a little violent at times, with the fire and destruction of the meteor shower and with dinosaurs fighting and sometimes eating each other. I think some of these scenes would be a little frightening for young children. This violence is the only reason for the PG rating that I could find.
The overall message is good. Aladar has a good heart and not only saves himself and the whole herd, but he finds love also and starts a family with another dinosaur. They show how compassion and hope are important and rewarding, and how one person (or dinosaur) can make a difference!
