I walked out of "World's Greatest Dad." Only time I've ever walked out of a movie.
It was that Robin Williams movie that was advertised as a relatively mischievous romp, but those who have seen the movie know The Scene I'm about to reference.
The events of the movie kick off when Williams walks in on his son having accidentally killed himself by asphyxiation. Williams absolutely crushes the scene, but it is an emotionally devastating scene, that is punctured before and after with a stupid comedy that doesn't do anything.
That scene comes out of nowhere and ruins your damn day. And the movie around it doesn't justify it.
In a more serious drama, I would have forgiven it, I think. But it was so unearned, and Williams sells it so well. I walked out 10 minutes after, when it was clear this was going to be a stupid movie with no point.
Trigger warning:
