At the core, it is still pretty much a typical dumped-before-Christmas movie, but it adds a little twist that sets up some endearing moments. Jessica was going to send her boyfriend 5 Christmas cards on successive days, but being dumped, she changes her plan. Instead she sends one card to each of five people that were important in her life. The cards bring some surprises to these receivers.
The dialogue, especially between Jessica and Luke, was lively and fun. Combine that with Jessica's optimistic and generous qualities and it makes this a nice romantic movie.
We follow three other couples and a fading boy-band celebrity. Spreading the story among 5 people and the people around them is both positive and negative for me. The positive is seeing what follows receiving the card for these people. The negative is that it diverts screen time from the central characters, Jessica and Luke. It's done pretty well, so the down side was minimized.
There are musical mini-performances. One is a short cello instrumental and the other is an original song by the boy-band although the latter is distracted by a conversation.
I could say it is a typical Hallmark ending, which it is, but some of the things that might be part of a typical ending are spread out a little.
