It's not repolishing as much as putting the damn thing together to my satisfaction. I criticise my work as I go, and I generally avoid restarting a draft completely from scratch if I can help it. But I am currently working on a story that I might be able to finish in time. I've done, as of this post, 6000 words. I think the problem will be getting it up to length, but I am reusing elements from other stories, as well as characters.
It's a serious novel, and it posits as to whether a mythological creature (or rather, several) was real. What they are will have to remain a surprise, but let's just say that it's one not often used in fiction.
And hey, at least Michael Logan gives two justifiable reasons for the infected animals trying to rape everything in their path: because it helps spread the virus, and because the scientists working on the virus thought it was funny. Gross as the concept was, I accepted that. I didn't expect Mr Brown to have a tragic backstory either. He just seemed to be doing things for laughs more than for Britain's wellbeing. Whereas in
The Stand, you at least got the feeling that, as dickish as the people covering up the viral outbreak were, they were trying to do something right, despite the fact that they were doing it the wrong way. They felt human, whereas Mr Brown felt more like a psycho who had been fired from the Umbrella Corporation.
