THEN
The requisite CW angst works really well between the brothers, perhaps moreso than it does on any other show on the CW lineup. Also, these guys hunt monsters. It's fun, grittier, and less polished than most CW shows. Despite the inherently formulaic nature of the show, it soon reveals a larger plan, and the season finale cliffhanger leaves people itching for more.
NOW
Thirteen seasons later, this plucky little show has a cult following (seriously). Sitting at a 2-3 million viewership, Supernatural has respectable enough ratings to keep itself on air, but only just. Yet this show has turned into a phenomenon that shows no signs of stopping...and this has everything to do with its rabid fan base.
As a fandom, Supernatural can only be described as...scary. We besiege pollings for awards, influence plots of episodes, are one of top two fandoms on fan fiction sites, have successfully lobbied for the return of beloved characters, and have even successfully campaigned for a spin-off that caters to our preferences. We appear to be everywhere, taking over Tumblr memes and Reddit threads with a speed that terrifies other fandoms.
Let that sink in for a moment. Other fandoms are scared of us.
What inspires such devotion in a television series...or anything, for that matter?
Well, for one...music. ...and lots of it.
