The song is, yes, totally perfect for the fandom. I mean, really, it could not be more descriptive of the B/K relationship.

But the evil of the vid comes in its accessibility; you don't need to know the fandom to get the vid. (I mean, really. The first time I watched it? I had no idea which guy was Keller and which was Beecher.) I suspect that your relative unfamiliarity with the fandom is responsible for that. People who are very deep into the fandoms they vid tend to choose shots that have great meaning - provided you're intimate with the canon. You picked shots that stand on their own, that have meaning whether you've seen where they come from or not. (Of course, you were probably helped by the incredible good acting in the canon; those guys are who they're playing every second, and it really shows in that vid.)

You can also see this kind of thing at work in a lot of the better movie vids, especially the movies that don't have huge fandoms. The vids are much easier to get than most TV ones, and, again, I think it's 'cause the vidder didn't know the movie quite as well.

(Although it is almost criminally unfair that you aren't reading Ozfic. Your viewers certainly are.)
