Sansho The Bailiff is a great movie, but I doubt I'll be upgrading the DVD version anytime soon. The rest of these choices don't do a whole lot for me.
The Criterion Collection has announced five titles for Blu-ray release in February. On February 5, the studio will release The Ballad of Narayama (Keisuke Kino****a, 1958). A week later, it will release The Kid With A Bike (Dardenne Brothers, 2011). On February 19, it will release On the Waterfront (Elia Kazan, 1954). On February 26, it will release Chronicle of a Summer (Jean Rouch and Edgar Morin, 1961) and Sansho the Bailiff (Kenji Mizoguchi, 1954).
