I don't understand what "The Last" stands for in this movie's title. Maybe its predicting that this is the very last Zatoichi movie that will be made ? Who knows, but it's unlikely that this would be the last time popular character of Zatoichi will ever appear on screen.
Shingo Katori's version of Ichi lacks the creepiness of Shintaro Katsu, and Takeshi Kitano's version, but has much more modern looks and feel to it. Consequently, he appears too nice, and couldn't infuse enough menacing character to the role. The fault in my opinion is not with Katori, but the casting director who've cast Katori for this role. Katori is a good actor, but his strength is in more modern roles, or if he was 10 years older, he would have looked more the part.
The story wasn't so intriguing either. It didn't have to be a Zatoichi's movie to tell this story. The grittiness of the original is missing, and lacks the feeling of the downtrodden in the society. The transformance from the downtrodden to the super swordsman of usual Zatoichi movie is also lacking. What's too many of in this movie is senseless thrashing of people by the bad guys..
So while acceptable, the movie turned out to be mediocre in many ways, and can only be recommended for viewing by a die hard Zatoichi fans.
