We have become so accustomed to the twist ending that some film critics seem to dismiss films from recommendation for no other reason. I consider this a "sixth sense" effect, referring to M.

This Halloween-themed episode from 2014 celebrates one of the best. 

Introductory material encourages voting in 2020, even from registered voters who despair for one reason or another.
