<How I see it is that for the first time in a while, Marge is once again a three-dimensional personality and not just a nagging, naive mother.>
I don't know. Marge doesn't really nag at all. Since certain Season 9 +10 episodes and the near entirety of 11 and 12, she's turned into more of an Edith Bunker persona. She wasn't really that 3D, but more just putting her good intentions to good use. She isn't the intelligent character she used to be awhile ago.
