It is me, too. It's the setting, not the hackneyed story.
The story between each couple really didn't have to do with autumn, other than the piece the quartet was working on was Vivaldi's "Autumn", so I'm guessing that's why the story didn't put you into that mood. With typical Hallmark holiday fare, not only the setting goes with the holiday, but so does the story. A woman moves from the city back to her small hometown to save the local candy cane making business that was founded by her grandmother.
I understand why some people can't stand the story-telling, it's far from ground-breaking TV. I also see the appeal that others have for it, and they sometimes appeal to me. Sometimes I just want to see some silly 'fluff' with a happy ending that makes me feel happy.
I'm someone who has always liked the change of seasons, and I find my TV viewing can follow the seasons. I may start giving Hallmark more of a chance this month, as it's the start of Autumn, which I like. October gets switched to SyFy and horror movies for "spooky season". November goes to harvest and Thanksgiving, December is Christmas and New Year's with Hallmark.
When Spring comes around, I don't watch Hallmark as I'm not fond of Spring. The same for Summer.
