Great to hear that they did a good job on the DVDs, as that's the set most people are likely to buy.
I agree with your observations about Betty Draper's arc in Season Two, and I think it's a shame that January Jones didn't also get an Emmy nomination along with Elisabeth Moss. They both gave extraordinary performances that spanned the entire season, but I suspect Moss's performance hit harder because it kind of sneaks up on you. Betty's trajectory is a more familiar one, but I still found Jones amazing at conveying a woman who one day realizes that not only is her husband a stranger, but so is she.
