Film and Manga are two different things. Film captures motion that is harder to represent in ink and paper, thus the storytelling will be different. What you're trying to compare are two different types of storytelling and don't tell me that it's the same anywhere coz that would only show how narrow-minded you are..
Also, if you think I don't know the name Kurosawa simply because he's the a rare great japanese artist on the top of youre head in your field of expertise, then shame on you. Even a manga enthusiast like me know the name of the director of Seven Samurai. The film which later became was the main influence for the anime "Samurai Seven." You should have used someone harder like Tetsuji Takechi.
Like I said, you're exposure to the culture is lacking if even someone like me who doesn't watch TV too often, has no time to browse the internet too often, don't have access to any manga published, and only can depend on the 2 hour breaks to download scanlations to be able to read manga knows the who's who of other fields besides manga in japan.
Also, you're co-notating my earlier post in the wrong way as well. You may have been exposed to japanese culture but that wasn't the point. The point was you didn't understand the way japanese humor worked in japanese culture, hence you lack exposure to it.
