Kitano's remake of the popular 1960's "Zatoichi-the Blind Swordsman" series (there were probably over two dozen of the original series) takes big risks but largely succeeds. Kitano is a darker, more sinister Zatoichi, and the action is a lot more Tarantino-esque. The sword action is first class but extremely violent, unlike the original series which, like the vintage Westerns, were mostly bloodless affairs. Blood squirts everywhere on the scale of "Kill Bill."
This is not the 1960s Zatoichi, who was a more light-hearted character who often avoided conflict and was even prepared to play a buffoon to avoid violence. Not so here - Kitano stalks his prey relentlessly, like the former Yakusa he was. There is a very adult story spliced in here about the two gisha runaways (one is not who s(he) appears to be) so forget about pre-teens watching this one. Unlike many Samurai period pieces, there is a plot here which is serious and sad.
The unexpected bonus to this movie is the excellent musical soundtrack consisting of Taiko drumming and dancing, well worth cranking up on a home theater system. Peasants threshing rice beat out a syncopated background to a scene, and there is a big Taiko musical send up (not too different from some of the 1960s Zatochi musical numbers) at the end.
