Closing out the year on a nice positive note, This is a typical Christmas "need to change your outlook" kind of a story as exemplified in books such as A Christmas Carol, and in movies such as It's a Wonderful Life which I took delight in parodying last year, and Miracle on 34th Street, of which I think the original was better than the remake. It involves a couple falling in love in only two or three days, and a very pushy woman winning over a determinedly anti-Christmas single dad. So why did I like this one, and reject the other one I'm reviewing today? It's a matter of perspective. The other one put a completely unrealistic plot into a real life situation, and this one put a perfectly plausible plot (in the story context) into a fantasy. The latter works. The former never will unless you're writing an absurdist comedy and not a romance.
It's the very fact that this is a ridiculous fantasy that means you don't take it too seriously, which is why I don't get some of the negative comments I've read about this. It's like complaining that Cinderella would have been far too uncomfortable in glass slippers (when they were, in the original story, fur anyway!), or that wolves can't even talk, much less huff and puff, and blow down a house. You can't judge it seriously, and like a children's story, you need to accept it within its own frame of reference, not in some adult reality frame of your own invention. It feels rather like these critics are trying to argue that you can't change a young suicidal person's mind, so leave 'em alone and let 'em get on with it!
No, you don't let an otherwise perfectly healthy young suicidal person get on with it even if they really want to, and in a world where Santa is not only real, but has a family, you can't let a guy rob his kids of the fun of Christmas. You have to hold an intervention! This is why I can like this story and reject the other one, because within its fantasy world, this story was plausible and fun. Yes, Santa's daughter was pushy, but she didn't want to be there in the first place, and was focused solely on getting this task done and moving on. She never expected to be won over by this single dad's love for his kids or his level of patience with her. It wasn't great literature. It wasn't authentic reality. It was a fairy tale, and it was cute and fun and funny, and I liked it. That's all there is to it.
