I'm not doing it just because of Michelle. If that was the case, I would dislike season 5 so much. I just found a lot of episodes by that time to seem more tired and the overall charm seemed to go down for me. As boring as some of the earliest episodes were, I liked the characters in general. I wasn't a big fan of all the new minor characters coming in.
