Many of the following movies were central to my childhood, having grown up in the early 2000s. Unfortunately, almost all of these movies are under appreciated and, as a result, forgotten.
The Incredibles
A Pixar film about a superhero family. It is finally getting a sequel in 2018!
Spirited Away
A story that is surprisingly dark for a potential children's movie where a girl's parents turn into pigs and she goes on a quest to change them back. Along the way, she makes both friends and enemies.
The Emperors New Groove
The story of a selfish dictator and some hilariously evil disgruntled employees.
Chicken Run
One fearless, clay-mated chicken dreams of escaping from the chicken coop and takes the other chickens with him.
Howl's Moving Castle
The story of a young girl who is cursed to live in the body of an old woman seeks help from her friend Howl, a sorcerer, who tries to cure her.
Treasure Planet
A young space treasure hunter finds a map to the universe's greatest treasure.
Robots
A young robot enters adulthood and heads to a new city on his own. Along the way, he makes new friends and uncovers an evil scheme.
Spirit: Stallion of the Cimarron
Told from the point of view of a horse, this movie is the story of the domestication of wild horses. This movie also has one of the best soundtracks ever!
Honorable Mention: The Iron Giant
This is the story of a young boy who befriends a giant robot that the government wants to destroy.This movie was actually released in 1999 but it was one of my favorites as a kid. In fact my favorite quote "you are what you choose to be".
All of these movies are amazing and I would recommend watching every last one of them!
