I've seen a lot of people complaining about books whose main characters are "blank slates," and I'm a little curious what you guys think of that. Obviously a character needs to have...well, character...or else they're nothing but mannequins that "plot" happens around. But if you give them too much, you risk the reader having trouble identifying with them. They need to be able to picture themselves as the main character, which becomes harder the less they realize they have in common with them. So obviously there needs to be a balance between having too much personality and too little. Where do you think that is?
