We just went to see Guardians of the Galaxy, part 2 (loved it, by the way!). I won't give any spoilers, but it was so well done, I didn't really notice when the black moment happened. But now that I look back on it, it followed the three-part play setup, with the black moment right before the ending.
Have you ever noticed the black moment in a movie or in a book? Romances are pretty easy to figure out when the black moment comes. The main character (usually the heroine) loses everything, just to be saved by the hero.
Let me know if you've ever noticed it. It'll give you more of a sense of satisfaction when things go right again at the end.
Have a great week!
