#4 – Supernatural
Since it began in 2005, this CW fantasy drama has had some of the most adoring fans out there. It follows the lives of two handsome, brooding brothers and their fight against demons, monsters, ghosts, and pretty much any other awful thing you can imagine. It also has a lot of angst, humour, and cool special effects.
Supernatural fans are devoted, and have a fondness for attending conventions and discussing the show’s mythology in depth. The show has a couple of subreddits, hundreds of Tumblrs and fanfiction sites, fan art all over Pinterest, and more. There are even official tie-in novels and comics to keep fans happy between seasons. With the tenth season due to start in October 2014, it’s best to stay away from the web if you’d like to avoid spoilers. The fans are very, very excited.
