Continuity mistake: Near the end, Mike is hanging the glass angel he got from Artie on the tree. Nina comes in through the front door, leaving the door chain hanging (unlatched), yet, in the very next shot the chain is on.
Other mistake: Rose's secretary tells her that Rose's sister couldn't spend Christmas with her. But in Rose's mother's hospital room, all of the childhood pictures she points out shows a girl and a boy, not two girls. One could claim that they also had a brother, and that there was never taken any photos of her sister, but since the whole story is about the fact that Rose doesn't have anyone to spend X-mas with, wouldn't she call her brother if she had one?
