In 'Pinocchio', the little puppet's journey is filled with hardships. He has to constantly struggle not to be led astray by bad influences like the fox and the cat. And every time he tells a lie, his nose grows, which is a symbol of his moral missteps and the consequences he faces are quite sad in a way.
One common element is the senselessness of it. Often, there is no real 'reason' for the murder that seems justifiable. For example, in random killings on the street.
External factors often play a big role. Like in Romeo and Juliet, family feud, or in stories set in different historical periods, social class differences can prevent two lovers from being together. These external forces create a lot of obstacles for the love to thrive.
In 'Snow White', the Queen's jealousy drives her to such extreme actions. Her own insecurities lead to her downfall. It's sad to think that her own self - loathing and envy caused so much chaos and ultimately her death. Also, Snow White was forced to flee and hide from her stepmother, which was a difficult situation for her.
In 'Bambi', the death of Bambi's mother is extremely sad. She is shot by hunters while Bambi is still a young fawn. This moment is a shock to the viewers and Bambi, who is then left alone in the forest, having to face the harsh world without his mother's protection. It's a story that shows the cruelty of the outside world.
The story of 'Pinocchio' has its sad parts. Pinocchio is constantly getting into trouble and facing the consequences of his naivete and disobedience. His journey to become a real boy is filled with hardships. And in 'Dumbo', Dumbo is separated from his mother and bullied for his big ears, which makes it a sad Disney story.
Definitely 'Up'. The beginning where Carl and Ellie's relationship is shown from their youth to her passing is so emotional. It's just a few minutes but it really tugs at the heartstrings. Another one is 'Beauty and the Beast' when the Beast is dying and Belle is crying over him. It's a really sad moment.
One really sad story is about a little puppy that got lost during a big storm. It was separated from its family and was all alone in the cold, wet streets, shivering and scared, not knowing where to go.
Often, there's an unexpected event that tears the lovers apart. For example, an accident causing memory loss. Also, sacrifice is a part. In some sad love stories, one person sacrifices their own happiness for the other, like the girl with the terminal illness who let the boy go. And time can be a factor too. Time passing and things changing can lead to a sad end of a love story.
In 'Beauty and the Beast', there's a bit of a sad undertone. The Beast was cursed because of his own arrogance and pride. He was living in isolation, shunned by society, and it took a long time for love to break the curse. He had to endure years of loneliness and self - loathing before Belle came along.
In the story of Princess Jasmine, she was restricted by the rules of the kingdom. She wanted to marry for love but was forced to consider a suitor for the sake of the kingdom, which was quite sad. Elsa from 'Frozen' also had a sad backstory. She was isolated from her sister Anna because she was afraid of her powers harming others. This led to a lot of loneliness and misunderstanding for her. Aurora in 'Sleeping Beauty' was put under a curse which was a very sad fate for her to endure.
