It seems like the last couple of years that the new formula Christmas story is the quest to return something, possibly a keepsake, one of the leads found by accident. This story follows that formula pretty closely. The attempt to frame a conflict near the end was very weak on both sides of the relationship. I think Greg's excuse wasn't laid out well enough emotionally, and Holly overreacted to the situation. I'd like to expand on that but then it really is a spoiler.
All theses movies start with friction between the leads and in this case it was fairly mild, but Holly resisted Greg's persistent charm firmly, until she didn't. After that Brendan Penny and Ashley Greene developed a quiet chemistry. Other actors filled their roles well.
All of these quest stories give the viewer a mystery, but unlike some crime mysteries, the viewer doesn't know enough to jump ahead to the solution. However, the viewer can watch while the characters sleuth out new leads. In this case, many of the leads were related in a technical way to fine jewelry in the form of charms for bracelets. The mystery has a nice sentimental resolution. The romance story follows the expected formula. There are no great highs or lows. There's almost no tension in the form of any threat hanging over the main characters. Any surprises are in the form of the technical clues I mentioned as Holly discovers she jumped to conclusions that weren't exactly correct. A viewer with an interest to learn about this subject will find a bit of education.
A couple of side notes. 1 - Once again this web site doesn't recognize who the real leads are in the movie, as of this writing several days after the premiere. 2- Another reviewer claims that one of Greene's facial features "ruins" the move. I think that's a bit cruel and I thought Greene was quite attractive, hopefully someone we'll see again on Hallmark. We all see people differently.
