The most frustrating movie ending

[TinyFroggy]

What is the most frustrating movie ending you ever watched?

Mine has to be The Mist. It got me stuck in my head through all these years and wonder what I wil ever do when I'm in that situation. I am still wondering to this day.

The most frustrating ending to a film I've watched is actually also my all time favorite film.

That being being Inception.

Obviously throughout the film he is fixated on spinning his totem to ensure he isn't inside a dream, and refuses to see his kids faces in a dream as he wants to see them in real life for the first time. However at the end he walks away to go be with his kids without seeing if his totem toppled over or not, and the camera then cuts to the credits, leaving the viewer to guess for themselves as to whether or not he's in a dream.
