Do you think the readers are attracted more to the sympathetic good guy who are more heart-warming? Or the antagonistic bad guy who you'd just love to hate? I realise characterisation all evolves around plot. But personally the characters are of the upmost importance. Look at the 'Twilight' saga for instance. Do you think if there weren't a character without Edward Cullen (Robert Pattinson, the vampire, or lead character to those who aren't familiar with the books) in it? Do you think they'd still be as popular?
