Don Bluth's The Land Before Time is arguably one of the darkest children's movies ever made and yet, it's probably one of the 1980s cartoons that are remembered to this day and even beloved despite its downsides. Indeed, it's quite a charming story with its dynamic animation and likable characters.

What not everyone knows, however, is that the original animated movie had spawned an entire franchise with thirteen direct-to-video sequels with the first one released in 1994, six years after the original, and the last one released in 2016. Some of these were more successful than others and, consequently, were better received.

10 Journey Through The Mists (1996) - 5.8

Obviously, no other installment in the franchise can beat the original movie. With Steven Spielberg as executive producer, The Land Before Time could be considered the predecessor to Spielberg's Jurassic Park, though the animated movie can definitely stand on its own.

The story follows a group of five young dinosaurs of different species who become friends as they try to survive in the dangerous prehistoric world.
