I know this movie didn't get the best reviews ever, but it is just that many people are beliving that the movie is copy-catting "The Land Before Time". THAT'S NOT TRUE! This movie was created to show kids that they should get along in tough times, and be a team. Most people arn't getting that message.
Although this movie does have major flaws, it still is worth buying. What flaws you ask? For instance, the star of the show, Aladar, is an Iguanodon. The main villain in the show, is a Carnotaurus. Unlike the movie, Carnotaurus was much smaller than any Iguanodon.
But I reccomend you still buy it! It's really worth more than it is advertised.
