How not to edit a movie.
I just finished watching this movie where the mother in the back story died in a car accident, and one of the characters is supposed to be just like her. Then the final scene shows a car driving up behind to her in the background, and you're like "Oh shit, she's going to get hit!" and then the person watching her starts to tear up. Then in the next shot the car is gone and she skips off. Credits. I don't think it was even intentional.
