Movies That Fall Apart in the 3rd Act (Ending Sucks)

[curl-6]

I actually thought the last act of the Blair Witch Project was done brilliantly. The point was not to "show the Witch" because the core concept of the film is that there's no guarantee there even is a witch; it's about presenting inconclusive evidence to the viewer so that our imaginations fill in the gaps.

 

Anyway, some that come to mind for me are Gone Girl, The Descent, No Country For Old Men, Oldboy.
