Things Which Don't Make Sense
In the opening narration, Pa Ingalls states that these events took place over the winter of '96. That is not only plain wrong, it is absolutely insane. In Little House on the Prairie, Season 9, episode 20, the house fire took place in 1889, around September, at which time Baby Rose appeared to be about a year old. (She should in fact have been nearly three, but that's another matter.) In Bless All the Dear Children, Rose appears about two years old. No one else has aged more than a year either. If Rose was, say, a year old in 1889, she should have been eight years old in 1896! Everyone else should have been correspondingly older as well. This is almost criminally WRONG! This movie should have been set around Christmas 1890!
It is almost Christmas in Minnesota, yet there is no snow, everyone is wearing light summer clothing, and no one even puts on a coat except in the night scenes. The night scenes have loud noises made by crickets or similar insects which would not be active in winter.
Laura's recitation from the book of Luke is nice, but Linus did it better in A Charlie Brown Christmas. There are probably other things but there are some major points. Sorry I can't say better about this movie.
