Children's movies hold so many strong messages, but those messages are shrugged off simply because the movie was designed for kids. I don't know how many people I have personally talked to about how some of these movies could really hit hard if people would just watch them.
Warning: I'm trying to take as many spoilers out of this as much as possible, but to get some of the messages, there may be some.
"The Lion King 2: Simba's Pride"
This movie was the first movie I really picked up on the message. Simba sings "We Are One" to his daughter Kiara, but she is completely lost to the meaning. As her pride and the outsiders prepare for war, it begins to reach her that they all are the same. As the fight is full force, she (with Kovu) jumps in and tells her father "Them? Us? Look at them....they are us. What differences do you see?"
In this line, Kiara brings out the racism in the movie. The outsiders looked down on the pride and the pride looked down on the outsiders. When Kiara brings up that they are the same, both sides realize that they have been stereotyping each other wrongly. Every single one of them are lions.
"Zootopia"
The racism continues in "Zootopia," but in this movie, it is much more prominent. Prey outnumber predators greatly, and even though they don't admit it, the prey are terrified. This fear is not really touched upon until predators are seen going savage and Judy accidentally lets out it may possibly be biology causing them to act that way.
She starts to notice how prey are treating predators badly; protesting their existence in Zootopia, telling them to leave, not sitting next to them in public, etc. The sheep mayor uses prey's fear of predators to gain power.
In the beginning storyboard of "Zootopia", predators wore shock collars. They removed that aspect, but the collars would shock a predator if they became too emotional. Anger, fear, joy, any emotion that would affect them, they would be shocked to protect the prey.
This movie also has discrimination against species. Judy is constantly told she can't be a cop because she is a bunny. Foxes are labeled as untrustworthy, this is shown by multiple characters not trusting Nick.
There is so much more to this movie as well, such as stereotypes, but I need to touch on a few more movies.
"Inside Out"
This one is pretty self-explanatory. But many people don't realize that this movie is actually used by child counselors to help the children express their emotions. This movie made the emotions truly come to life in a way that children can relate.
Another movie that is similar by touching upon emotions is
"Big Hero 6"
I haven't actually seen the full movie, but I've got most of the story, I think. This movie deals with depression. Hiro's emotions take over him throughout the film, causing him to act irrationally, especially in the fight with Callaghan. His friends calm him down, understanding that his anger comes from pain.
But Callaghan is also fighting his own depression and anger, causing him to fight and try and kill Krei. This movie does good at showing how depression is not just someone being sad, depression is an array of emotions.
The last movie I want to talk about hasn't been completed:
"The Chronicles Of Narnia"
This one has a slightly different hidden meaning than racism or emotions. Narnia is a metaphor for God and heaven. MAJOR spoilers coming here.
The first movie, Aslan was killed on the stone table, but then revived. Just like Jesus was killed on the cross and rose three days later. Aslan is always there, throughout Narnia's ages. Even though he is a lion and was visibly killed, he still comes to people throughout the ages.
The third movie at the very end, as a group of people/animals stands looking at Aslan's Country, Aslan tells Prince Caspian if he crosses he cannot return. The mouse crosses instead, ready to end his journey. Aslan's Country is heaven. When you cross over, you die and are unable to return.
In the last book (now I know this isn't a movie, but it's still a big part of the series) Peter, Lucy, Edmund, and some of their other friends who know of Narnia are killed in an accident. They end up in Narnia just as Aslan calls upon Father Time. All of the creatures in the past and present have to make a choice, to follow Aslan or to leave him.
This is symbolic to those going to Heaven and Hell. A flood takes over the land and Peter closes the door, ending Narnia. Aslan leads them to his country, the true Narnia.
These are just a few of the extensive amount of children's movies that hold strong messages. There are so many more out there, just look deeper into the movies you are watching.
