Gottman was trying to brain storm ideas on how to manage to simplify the task of predictions. It was very frustrating for people to get this task because the films were very overwhelming.
Gottman after watching many films got so good at observing people that he could be in a restaurant and eavesdrop on a couple and get a pretty good sense on how there marriage is going. Others who tried using his method couldn't even find a pattern in 15 minutes of film.
