"The Land Before Time" is a classic kid's animation. It has a good cast of characters and a decent little plot. Sadly this film has been somewhat diminished in it's stature over the years by an onslaught of direct-to-video sequels that director Bluth had nothing to do with. The first film, however, is still very well made and heartwarming fun for the family. Don Bluth left Disney because the environment there wasn't conducive to making good animated films anymore, and I have no doubt that his leaving the company and producing animated films that rivaled Disney's in quality, and received more critical acclaim and financial success than even the contemporary Disney films of the 1980s, played a big part in Disney getting things in order and producing "The Little Mermiad" and the subsequent films of the so-called Disney Renaissance of the 1990s. Bluth may not been at Disney anymore, but I think he was a big factor in them getting their act together.
