Not only have all of Kurosawa's movies dropped considerably (Dodes'kaden went from top of the 100 list to an 8.08 average!) but Woman of the Dunes has dropped by .50 and all of Mizoguchi's films have dropped immensely (Life of Oharu and Ugetsu have both dropped off the list when they were both near the middle of it before, and Sansho the Bailiff has gone from the top to the middle).
