You just won't drop this, will you? Okay, then, let's play.
1) Name me three shows that lasted seven seasons (twelve if you include Angel) and
didn't violate continuity now and then. Heck, our much-beloved JMS broke continuty repeatedly. I'm even giving him a free pass on War Without End because of time constraints. But the simple fact is, he planned the five-year arc, started dropping hints about what he thought was going to happen, and then changed a lot of things as the arc progressed because they made more sense. And then there's the casting for Anna Sheridan.
2) Continuity is difficult enough for novelists to keep track of, and usually they aren't working on a deadline. Usually they can spread everything out in front of them, check their notes, etc. TV creators have to have a show on the screen on Day X, and they have to move quick for that. They don't have time to backtrack and watch every ep. to make sure they got everything squared away with everything else they've ever done. (They especially don't have time to go through and make sure their vampire never casts a reflection; there are too many reflective surfaces in the world.)
3) The only writers of the same scope and imagination of JMS, Whedon, and the others we're discussing who got anywhere near perfect continuity was Tolkien. He managed it by writing the Lord of the Rings (which is epic but not long) over a period of twenty years or so, and he didn't publish anything until he had it all perfect. Even then, he still had to change a few scenes in the Hobbit, which he'd written first, to bring that book into line. In short, the only way Tolkien managed perfect continuity was literally decades of painstaking labor combined with a little Soviet revisionism.
4) Continuity errors have a long pedigree. Look closely in the Illiad, and you'll discover that some poor sap gets killed two or three times. Similar to today's TV producers, Homer just didn't have time to go back and check everything. If you take the Bible, which is an even better comparison because (B5 being the exception) most TV shows are written by lots of people over time, much as the Bible was, you get loads of continuity errors.
5) Joss's continuity errors are usually small things, and for the sake of a joke -- or purely accidental, which, as I've just mentioned, is pretty much unavoidable. He made a few bigger ones, but again, it was because he'd thought of something better.
6) Continuity errors bug the heck out of me, so I get you. But I forgive them if the tale's well-told. I'd rather have a few errors in a brilliant story than have the creators say, "Well, we had
this awesome idea, which would have been inutterably fantastic, but unfortunately it would have violated the continuity of a scrap of dialogue that everyone's forgotten back in season one, so we couldn't do it." Continuity is
not the highest standard to hold a story to, although it's in the top three. There are things that are more important.
7) I'm a rabid Whedon fan not because I've drunk the Kool-Aid, or become hypnotized into joining his cult; I'm not going to defend him on every point, either. Season Seven left some things to be desired and equating magic with drug abuse really did kind of come out of left field in Season Six. My defense of Whedon is based in large part on love -- but I don't turn off my brain when I watch his stuff, okay? So don't imply that I'm a fool, like you did in your last post.
8) I wanted to let this drop. I acknowledged my sillyness in sticking up for the guy. I suggested we move this elsewhere. You decided to question my intellect instead, and if I'm not wrong, pulled out a nice ad hominem.
9) Everything I just wrote might be complete and utter hogwash. Maybe Joss Whedon is a bad storyteller because he can't address continuity errors and plot holes you could steer a ship through. Maybe you're absolutely right and I'm absolutely wrong.
10) Now, we're both being this guy:
so for f***'s sake, we're not having this conversation any more.
