What about Monroe? He seems a bit shadowy in the movie, but we seem to get the feeling that he was a patient and quiet man. He is likeable enough, although I don't know if he is a favorite.
A character that has always intrigued me is Lureen's mother. She is totally in the shadows, and we remember her for her hair. And yet, we can think of the life she must have led and would assume that she had always deferred to her husband. But there is so little known about her.
