Factual error: During the opening scene when the house is being shown, a nest hangs from the porch ceiling with live bees swarming around it. It is also snowing. The insects are honeybees, but the nest is a hornet nest. Honeybees don't make paper nests. Also, bees, hornets, and wasps are not active during the winter.
Question: At the end of the movie, Emily is greeted by the Virgin Mary who gives Emily a choice.
