In an era of brashness, crudity and general unpleasantness, the gentleness of “Downton Abbey: The Grand Finale” hits like a drug. If the ambition of putting “The Grand Finale” in the title indicates a dramatic sendoff, the reality of the film is much more patient. If “The Grand Finale” often feels like a wrapping-up, it’s also a statement on the very real possibility of merging modernity with tradition. Maybe “The Grand Finale” contains an instruction: You need not have a title to live well. My Rating: 8/10“Downton Abbey: The Grand Finale” is now playing in theaters.
