Christmas aside (it was a minor part of the story and actually could have been Thanksgiving or no holiday at all), this is a sentimental story about balancing family, friends, work, and personal ideals.
Our protagonist has a lot going on: work, husband, mother, and house--as well as fear.
I love the genre of going back in time or into an alternate dimension. It's always fun to see the individual in flux while getting familiar with the new setting into which they have been magically placed.
Self-discovery is always interesting to me and I found the ways of the protagonist's learning in this film to be unique--we're talking tear-jerker potential.
Endings and new beginnings. Love and loss and love. A romcom happy ending.
