They're Targaryens. Maybe they are all vapid empty husks of human beings and there is nothing to flesh out. They are rich, spoiled and entitled. Outside of the dragons, the current generation of Targs kind of suck. I doubt we're going to have any "OMG, they cut Eddard's head off!" moments in this series because none of them are all that likeable, honorable, or humorous at this stage. We know from the books that damn near every single character in this series is going to die. Unless we find someone to root for, and I don't believe I ever took sides while reading the book, this might be an entire series full of satisfying Little Finger and King Joffrey deaths and very little Eddard and Hodor deaths. Is there one character we've met yet where their death would affect you emotionally? I can think of a bunch from GOT. I'm not even sure character development would help with these people. These are mostly shitty people doing shitty things. Fuck 'em. Bring on the dragons and let's start killing them.
