Supernatural: 10 Perfect Episodes

Throughout its 15-year run, Supernatural brought back many fan favourites, but no return was as good as Chuck Shurley's return that confirmed the popular fan theory of Shurley being God. While Sam and Dean deal with Amara and her version of Stephen King's The Mist, this episode shifts focus to Chuck and Metatron having an almost hour-long heart-to-heart as Chuck writes his own autobiography.

The episode explores the unanswered question of where God has been; it turns out he had been travelling, joined Snapchat and started a blog full of cute cat pictures. It also answered the question as to why Chuck abandoned all his creations, after seeing the conflict both humans and angels created, Chuck walked away to let them sort it out for themselves. Don't Call Me Shurley also discusses the nature of storytelling, with Chuck even mentioning he started a new book series called Revolution, which, of course, is a reference to Eric Kripke's short-lived series.

For fans, the episode provides a philosophical and metafictional treat. The very meta-discussion leads to Metatron defending humanity and making God feel guilty for his absence, convincing him to join the Winchesters in taking down his sister.
