In the process of consuming entertainment (tv shows, podcasts, stories, etc), a subject can become obsessed with seeing the end goal completed. With the end goal never getting resolved, the subject becomes hooked on the hope of the next episode. A common symptom is the subject believes that the next episode coming up is going to be the episode where they complete or prove what the series is documenting.
