They're popular because fans of the show really wanted to see them together. Their relationship on the show had so much potential that wasn't fully explored, so fanfictions give the opportunity to fulfill that wish.
One great fanfiction could be 'A New Beginning for Luke and Lorelai' where they finally realize their true feelings during a town event. It beautifully captures their chemistry and the essence of their relationship.
Michel could be one of the popular characters. He might be giving his very sarcastic yet endearing comments about the baby. And Taylor. He could be trying to enforce some town rules regarding the baby, like making sure the stroller is parked in the right place or that the baby doesn't make too much noise during town meetings. His over - the - top personality can create some interesting interactions in the fanfiction.
I'm not sure who the absolute best is, but some popular ones might be those who really capture the essence of Lorelai and Luke's relationship. They might be the ones who write about their small - town charm and the unique dynamic between them.
Love and communication are also big themes. Their relationship has its ups and downs, and fanfics often show how they work through misunderstandings. For example, Luke's reserved nature and Lorelai's more talkative and emotional side can sometimes lead to miscommunication, which is a common plot point. Also, the idea of second chances is prevalent, as their relationship has had its share of breaks and reconciliations.
