My immediate suggestion is to change the title to "The Case FOR Jack Kirby" - which is more positive.
That said, I will read this large work and enjoy it. Are you looking for feedback and discussion on your assertions?
You're right about the title. I was just feeling click baity.
My original plan was to write a book about Kirby's writing, and that's still my goal. This is just a sort of prequel.
Actually, part of the reason for writing a "case against" is that I am surprised that nobody has done so before. We have the "Lee did everything" book (Origins of Marvel Comics) so it seems fitting to have a "Lee did nothing" book. My current feelings are very negative to him, but my feelings have changed in the past, so they could do so again.
And I know that, while we humans like to pretend we are rational, we really are not. I currently don't like Lee for emotional reasons: I happen to love everything Kirby did. So changing Kirby's work is an unforgivable crime! And since I think Lee's changes are worthless, that means Lee cannot be called a writer, so that makes him a liar and cheat for taking the writing money. But obviously if I preferred Lee's writing to Kirby's then changing Kirby's writing would not be a crime, it would be a great service to mankind, and Lee would deserve every penny.
