I said it in the other thread, but the more I sit with it, the more I love it.
I thought the way that Luke & Lorelai were handled worked really well. I can relate to the idea of just kind of being comfortable and happy with where you are but not stopping to really give your overall life much thought and then realizing that years have gone by. Not 9, but still. You just live day to day and don't stop to think big picture because you are happy and don't necessarily feel like anything is missing. That seems true to their characters to me. The surrogacy storyline never seemed like a serious one to me, it was more to drive Lorelai along her journey of contemplating her life and questioning if she really made the right decisions. Because, ultimately, I feel like if one of them had REALLY wanted to have kids, they would have had them. Neither seems to have been pining for a baby.
