I do think some of my other characters come off pretty well, and I do like how the "Final Girl" bit comes out. So if it's a failure, it's a failure with some interesting bits.
I think that's a difference between my younger self and me today: ten or twelve years ago, I was convinced that everything I wrote was absolutely great, even if it was really shit. Now, I fully realize that I am capable of writing shit, but it's not traumatic; if my writing fails, I can still see the result as interesting, or at least educational. Not that I wouldn't prefer to write great stuff all the time, but if I fail, it's not horrible. This applies to other people's writing, too; I don't get offended by bad work as much anymore, because often as I learn things about what works and what doesn't, and that's interesting in its own right. The right kind of crap offers its own sort of pleasure.
