About the leaning thing... If I remember right, in the Talking Dead or somewhere else Jeffrey Dean Morgan said he had watched from the comics, how Negan stands, moves and makes any gestures, to make his acting similar as the comic book. I haven´t seen the comics except some pics in internet, so I don´t know how much the comic Negan leans back but I believe it´s his way to get in character?
I must say I hate Negan, but in that way it is kind of fun to hate him. He is so disgusting that it is actually entertaining, I just regret nothing bad really happens to him. Hopefully spring will change that. I´d love to see him getting surprised by nasty things he couldn´t help.

Such an odd character he is, but more funny than scary, and charming too in some odd way. In comparison, I hated Governor in different way, I really didn´t want to see him at all. He was purely mean and even when he had chance to show some kinder way, he messed it up being more like wanting to "own" people than really having any kind of relationship. I hoped to see him to take a new way with Lilly and the little girl and start over, but blah. No chance.
