I don't think I watched the first episode when is aired back in October of 2006, but I know that by December, I'd seen ALL of Season 1, and I was flailing wildly in anticipation for Season 2.
Other than PotC, this is the fandom that really showed me what it was like to be part of a fandom community. This is one of those fandoms where I'll jump into -land communities without a second thought, sign up for Big Bangs and other challenges, and drive all over Southern CA so I can meet up with people I've only talked to online. Of course, this is also the show that showed me just how much I'm prone to crying over character deaths, the show that made me weep copiously and embarrassingly in front of EVERYONE more times than I can count. It's the show that made me so furious I had to pause the download and rant at it for every episode of the third season, and it's the show that killed everyone I loved most in sometimes narratively unsatisfying ways.
But then... it's the show that gave me one of my most beloved OTPs, made "I'm not being funny, but..." part of my everyday conversations, made me smile every time I think of Allan being good with nuns, and made me melt every time I think of Certain Lines that Certain People Named Guy utter before riding back into Nottingham and Certain Death. (Except the death isn't really certain because this is RH and not ASoIaF.)
This is the fandom that made me write long fic again after only writing drabbles and vignettes for a long while. (And yes, I WILL write that Wolf's Head sequel one of these days... just not this year. Maybe next.)
This is one of those fandoms that, if we share it, will instantly make me want to be your friend.
This is one of those fandoms that, if someone says, "Hey, I'd kind of like to watch that show..." I'll be there on the couch next to them with my DVD's in hand faster than they can blink.
I guess what I'm trying to say is... I love this silly little show, and I LOVE its awesome fandom. You guys are the most wonderful, thoughtful, creative people I could have asked to associate with.
