What is Supernatural? Supernatural was a TV show that ran from 2005 to 2020 on CW. It followed Sam and Dean Winchester who grew up hunting monsters after the unexplained death of their mother, and carry on the legacy when their father goes missing.

By no means is Supernatural a niche show, having ran way past it's expected time, stopping at the fifteenth (15th) season. The popularity grew primarly on tumblr, but it did have a pretty big impact, having been referenced in other shows.

Why Supernatural? It's not a perfect show (though, truly, nothing is). The show is most definitely a capsule of it's time, and a few bits of bad tropes dashed in but the plot holds well; two brothers (and a few others) fighting the supernatural.
