I think I would call Night Music a romantic comedy. I don't know if you are familiar with an old movie called The Ghost and Mrs. Muir? It is an older film. It's more about the romance than it is necessarily a horror flick.
In that year [1865] John Muir offered to buy from his brother. . . a sanctuary for the wildflowers that had gladdened his youth. His brother declined to part with the land, but he could not suppress the idea: 1865 still stands in Wisconsin history as the birth-year of mercy for things natural, wild, and free.
