With deeply flawed protagonists? And all that?
While not a deal-breaker, the surrounding story will need to be really, really, really good to get past this particular hurdle with this particular editor. As mentioned in my Snellerview, I like my heroes heroic and my villains villainous. The single biggest reason I couldn't stand The Tommyknockers
was the hopeless yutziness of the protagonist. I want to be invested in these characters, to care--preferably deeply--what happens to them.
The way many "deeply flawed" characters are written, I tend to wish--like that man who wasn't there--they'd just go away.
Not the author's desired response, I'm sure.
