Don't watch this movie if you regret giving up your childish side. Inside Out will eventually make you feel good about who you are at the moment, but there are a good 15 minutes of this movie that will completely destroy you emotionally.
Rue, The Hunger Games
If the hunger games were real, this moment would get them canceled immediately. Every character's death holds a significant amount of weight, but Rue's death hits a little harder than the rest. If it weren't for the death of Rue, The Hunger Games would have never ended the way Katniss wanted them to.
If you thought Rue's death was sad in the movies, you shouldn't read the books. We're talking 15 whole pages documenting Katniss's emotional turmoil revolving around Rue's death.
Han Solo, Star Wars: The Force Awakens
In a mirror depiction from the original Star Wars trilogy, Ben Solo murders his father in the same way that Luke Skywalker did. Seeing Harrison Ford die on screen is one of the most painful sights that anyone could witness. However, as the story progresses, Kylo Ren gets his just desserts.
