Thank the Great Pumpkin.
You see—bear with me, I swear this is relevant—I'm a Counting Crows fan. Their first album, August and Everything After, was perfect. Maybe not every song, maybe not every lyric, but as an album? Perfect. The sort of album you can listen to over and over again, finding new things, making new discoveries about the way the songs fit together, the stories that the lyrics are telling...perfect. So naturally, when their second album was released (Recovering the Satellites), they got basically panned. Why? Because Recovering the Satellites was a bad album? But it wasn't. It was actually a really good album, with a lot of really good songs. So what was the problem?
The problem was that it wasn't perfect. And once you've been perfect, people are going to start expecting perfection every single time. It's the dilemma of the student who manages straight As on a report card—once may be amazing, but when you bring home that B+ next quarter, there are going to be some pointed questions directed your way.
Now, I do think that a few of the things some people view as flaws will become less flaw-like as the series goes on. At the end of the first episode of Veronica Mars, you don't know who killed Lilly Kane, who raped Veronica, or what happened to her mother, now, do you? I'm absolutely working to make sure every Toby book has a satisfying conclusion all its own, but there are going to be some narrative threads that take a long, long time to be resolved. I'm actually crazy-careful with my timelines, and with making sure that all my guns are on the mantelpiece as soon as they need to be, just so there's no "but wait, there was no six-fingered man in the plot last season."
Yes, I will tell you who killed Lilly Kane.
Yes, I will tell you who raped Veronica.
Yes, I will tell you why every little piece of importance is important. But it's going to take a while. And I will, thankfully, probably never be perfectly perfect in an individual volume...although I, like the Counting Crows, really hope that my album (or series, as the case may be) is close enough to perfect when it's done that the flaws are forgiven.
