Imagine if Zatoichi the Blind Swordsman had an adopted daughter that was also blind and that he taught his sword skills. Also imagine that he left her at goze house as he went out on his travels, and she grew up to be a skilled musician. That's basically Ichi, a satisfying spin on the long-running saga of the blind swordsman.
The plot centers on Ichi's search for Zatoichi (who has been missing for quite some time), her tragic back-story, a feud between two yakuza gangs in an inn town, and a traveling warrior that eventually befriends Ichi. Haruka Ayase makes for a good (and absolutely gorgeous) Ichi, and plays her as soft-spoken, reserved and stoic while letting her determination, dangerousness, and lighter side break through when appropriate. Ayase is also great in the action scenes, which are pretty well done and bloody without crossing the line into gory.
I liked Ichi. There's nothing groundbreaking about it, but I enjoyed the characters (even though the antagonists are unfortunately two dimensional) and the balance between fighting and character development/story is excellent. This isn't a pure action film by any means, it's fairly leisurely-paced outside of action scenes (Ichi doesn't play around with her enemies). There's more than enough here to make the story of the blind swordsman(woman) worth visiting again.
