I'm rarely satisfied with movie endings...
For some reason, it takes something very special for me to appreciate a movie ending. It seems like a lot of movies either downplay or overplay their endings. And a lot of times, I find some endings too forced, rushed, or contrived. And I hate it when a film has a shocking ending or super plot twist, all for the sake of having a shock factor. As long as the ending lives up to the overall premise of the film, has a deep meaning, or makes sense...that's all I care about.
The most prevalent endings that impressed me, was the ending scenes to: Scarface, There Will Be Blood, Full Metal Jacket, Goodfellas, The Raid 2, American Psycho, The Shining, Under the Skin, Kalifornia, Training Day, Natural Born Killers, Fear & Loathing in Las Vegas
Just to name a few.
