The Soloist
Hero
We watched Supernatural from beginning to end. Seasons 1 to 5 form a cohesive concept. The series was designed by Kripke for 5 seasons. You don't have to continue beyond.That show was on for 15 years(2005 to 2020). That's insane.
After that, we tagged along because, like many long-lasting TV shows, the interaction between the main characters is more important than the monster of the week mystery. Some episodes are pure gold in self-irony or meta discourse.
There is a favourite episode in which a group of high school girls do a musical about the life of the Winchester Boys. There is a mystery at the school, and the real Boys show up. They end up watching the musical at the end.
There is also an animated Scooby-Doo episode. And the best is a Convention about Supernatural. The real Winchesters show up only to meet Cosplay Winchesters. No one believes they are the real deal. A very well-constructed and touching episode.
