I am new to the Zatoichi film series; this was the first film in the series I have seen, after buying a couple of seasons of the TV series and enjoying them. If the rest of the series is as good as this one then I can see I am in for a virtual lifetime of great Zatoichi films - when I can find them in video stores!
"Zatoichi in Desperation" is darker and as another reviewer said, more "heavy handed" than the TV episodes I have seen. The characters - the prostitute given a tentative freedom, the fishermen from the village harassed by the local yakuza gang, the 14-year-old girl about to be forced to work in the brothel and her little brother - are memorable and tragic. Their lives become intertwined with Zatoichi's by a twist of fate - an old woman who accidentally falls from a bridge, and Zatoichi's guilt resulting over it.
This intertwining of relationships, Zatoichi's humbleness despite his master swordsmanship, and the great photography is what makes the film (and the Zatoichi series!) special.
