Yeah. And on the one hand, I agree. But on the other...I dunno.
See, I think that storytellers...they make a kind of contract with their audience. "Come on a journey with me, and I will entertain you. Give me your attention, your focus, and your money, and I will tell you a wonderful story." And as audience members, we say "Ok, cool! Let's do this!"
So, it bugs me when the story is either not moving or is not entertaining, or ends poorly, and the storyteller in question basically turns around and says "Screw you. I don't owe you anything."
I'm not saying that Martin has done this, mind you. And I can understand that many storytellers -- as artists -- just figure they tried their best and used their best judgment. And in a sense, I don't think we're necessarily owed, as audience members, exactly what we want, at least in specific terms. I do, however, think that we're owed certain things in general terms. Like, we're owed a story that ends in a way that is largely satisfactory, and isn't some hackneyed ploy or half-assed explanation because the storyteller got bored. We're owed a complete tale, too.
It's that last one that I think bothers Martin's fans. Now, aside from people saying "But what if he dies before he finishes the story?" I don't know anything specific that'd make people think he's LIKELY to die before finishing. And so far, nobody's saying "But what if the ending....sucks?" Although, to be honest, certain story choices that Martin has made have not been of the highest quality (from what I can tell -- maybe he'll make them relevant later). But I think it's reasonable for fans to want him to finish the tale rather than say "Nah. I got bored. Figured I'd take up fly fishing instead. And hey, I don't owe you ****, fanboy." Although he hasn't said that, either.
I just don't fully buy into the artist-as-sacrosanct attitude that a lot of people have, where it's wrong for fans to criticize an artist's work or act as if you haven't given them your time, money, and attention, or -- having done so -- that you have no right to want quality product from them.
