"While 'Needful Things' is primarily a Stephen King horror adaptation focused on supernatural manipulation and dark desires, its narrative is explicitly set during the Christmas season in the town of Castle Rock. The presence of a strange, gift-giving shop named 'Needful Things' during this time gives the film a strong structural tie to the holiday, even if the themes explored are antithetical to traditional Christmas cheer. It leans heavily on the dark inversion of the season."
