Supernatural is at #11 on EW.com's 25 Greatest Cult TV Shows Ever:
11. SUPERNATURAL
(2005-present; The WB, The CW)
Premise: Two hot brothers (Jared Padalecki and Jensen Ackles) get in their hot car and vanquish all manner of demonic beasties. With style.
Why It's Cult: Because some members of the show's small but passionate fanbase have taken to writing fan fiction. And any show that inspires people to want to continue the heroes' adventures on their own time qualifies as cult. (We'll not mention that some of that fan fiction has the Winchester brothers doing things that brothers shouldn't be doing. It's called ''Wincest.'' Nuff said, ja?) —Marc Bernardin
