Let me explain. Movies that ended and you never saw the ending coming. Meaning, plot resolution wise you thought there had to be some 20 minutes left so when the credits start rolling, you’re sitting there saying, “Are you S**tting me? It’s over?”
I can’t think of any I’ve seen in a lonnng time, but I know there were a couple when I was very young because I remember my parents saying, “WHAT?!”
I don’t think “Empire Strikes Back” was one, but I do remember that sinking feeling when the music started swelling and thinking “Awwww nooo.”
“Tommy” may have been one.
