would you rather watch a movie till the end or miss the ending?
most people would say they would want to see the ending. But a study out of Harvard featured in a recent "Hidden Brain" podcast shows that people are more engaged, happier, and like a movie more that they didn't get to see the ending of.
Wonder and mystery let the story live on in their imagination. This is the same reason that if I'm really into a book, I'll just never read the very end.
Next time you watch a movie try not finishing it.
