Lorelai and Luke were actually very sensitively written for each other, except for the stupid plot points to create drama or the authors flipping their noses at the producers.
Luke loved Stars Hollow and its life in spite of his obstreperous behavior. He was a truth-teller, calling out absurdities, but he cared for individuals privately. Lorelai loved her chosen home. She appreciated the family feeling and enthusiastically participated in activities.
Lorelai stated that she wanted a partner, someone who would have her back and be there for her. Jason was his career and society. He didn’t think twice about sacrificing others for his goals. Christopher was the eternal playmate. Neither of them were there for her the way she wanted.
Luke wanted love, acceptance and a family (a wife for sure, kids after a discussion). Think “not gonna make you eat French food.” Lorelai was his perfect foil, bringing him out of his grumpy shell and having his back as well as challenging him.
If they hadn’t been written with the communication skills of 14 year olds, it could have been awesome.
