To my (somewhat) surprise, I have come to really enjoy her in this format. In her previous show, all of the segments were highly produced in a more 'lesson' format. While that format was a great one, her new show allows viewers to get to know her personality a little better.
While she does like things to be perfect, she does make mistakes and laughs at herself in the process. Even being a fan of Martha's, I honestly did not expect the candor she demonstrated regarding her time in prison. (I wondered if the subject would ever even be mentioned.) Instead, it has been to the forefront of many of her shows and she has even dropped several great one-liners to her guests about it.
Martha is clearly a very happy person who enjoys what she does and I believe has a renewed sense of spirit. That type of attitude is contagious and makes the show fun to watch!
