These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Crowning Moment of Funny: Numerous moments in the Takeshi Kitano film. Appropriate, since Kitano, the star and director, is a comedian.
Foe Yay: Between Ichi and Hirate in the first film. They see each other as Worthy Opponents and there is a scene where Ichi gives Hirate a massage. One of the more positive foe-yay relationships.
I Am Not Shazam: The protagonist's name is Ichi, Zato refers to a historical guild for blind men. Ichi should be called Zato-no-Ichi, but this is shortened to Zatoichi.
