Movie Endings That Left You Speechless

What are some movie endings that made you sit on your couch and made you just stare at the credits trying to process what you just watched? Some movie endings for me are like in Elephant (2003) where the shooter is in the lunchroom and sees a couple then points the gun at them saying “Eeny, meeny, miny, moe”, then the scene cuts to clouds, that scene always sticks with me. Another would be The Mist (2007) where David shoots everyone in the car just to come outside to see the army rescue everyone, this scene is so scary because seeing the guards come up to him looking confused knowing if he had just waited longer, everyone could have been saved.
