Lion King - not what happened. And Scar receives his due from the hyenas after demonstrating throughout that this is the result of a personal quest for power.
Bambi - not seen or anywhere so explicit. Hunter is doing what happens to animals. Moves quickly to happy adulthood.
Dumbo - all is happy ever after.
Hunchback - bad person does bad things for personal reasons, gets his just desserts at the end.
Encanto - Mass murder, possible ethnic cleansing, civil war/wartime atrocities - young woman spends the scene running in terror with her babies and other villagers having witnessed murders and then her husband sacrifices himself to give her time to escape whilst Colombian soldiers gallop towards him with swords making it clear how he will die, then they may have been killed by a magic candle turning into an IED. There's no reason given for the massacre, so true resolution, meaning that it could happen again (one of the reasons why the GM is so abusive towards her son and controlling of everybody). Also significantly more likely to have been or could become the experience of a number of children watching the movie, compared to being a young Prince, flying elephant or beautiful gypsy woman.
It's brutal in that what happened (excluding the magic) happens to children and their parents across the world every day and is directly relatable because they are human, not animals.
