When Brian is at the church for his piano lesson, he has a hairstyle with bangs. When he finds out that Sarah is missing, he has his hair slicked to the sides with what looks like gel although there was no time for him to have messed with his hair.
The Reverend asked Sully and Robert E. To help build the Manger. In a later scene, Matthew is borrowing tools from Sully to build the manger. The story line is inconsistent.
Fifi the "poodle" is not a poodle at all. She is a Bichon Frise. Poodles have longer snouts and legs. Fifi even had a traditional Bichon haircut.
The nativity is set for Christmas Eve in Colorado but the sheep's wool has been sheared off. Nobody shears sheep in the Winter.
Neither Mrs Sheehan nor Sara speak with a Georgia accent.
What Brian cut from the tree was not mistletoe, just a bit of tree branch. Mistletoes in Colorado are dwarf species.
It is a mystery as to how the tree rope wrapped around Sara's ankle three times.
Sarah and her mother moved from Georgia to Colorado. While her mother has a southern accent, Sarah does not.
Ann Marie and Sara have moved to Colorado Springs to restart their lives with Ann Marie's sister. Her only living relative. Why did she need to buy a wagon and horse immediately after arriving on the train? One would expect Ann Marie's sister to meet her when the train arrived.
When Brian asks for his first piano lesson and sits on the piano bench beside Sara, the Reverend suggests that the two could play a Christmas Carol. This is occurs a few days before Christmas. It is impossible to expect a complete novice piano player and a barely experienced piano player to play a duet so soon.
Within two or three piano lessons, Brian is reading complex music. This is completely improbable. Also, the Reverend is supposedly giving the piano lessons. He is never sitting by Brian to teach him.
When Ann Marie arrives in Colorado Springs, Colorado, she immediately buys a wagon and horse. She then proceeds to buy supplies from the mercantile. She said she is moving into her sister's home. She is buying all the supplies as if she knows what her sister needs. There is no evidence that she ever talked with her sister to know what was needed.
