The predictability is not the biggest problem, most of Christmas movies are predictable. What I found most annoying is the storyline with the doctor who literally did nothing wrong, was open and direct, liked her and told her so and just seemed like a good guy. After which he got dumped for DARING to say that the calendar might not be magic. I found the main character obnoxious, angry at the whole world and not seeing any faults in herself.
This is really bad, you guys, just don't watch it
