@Monkey:
Interesting to severe deviations.
It's more accurate to say Inoue has taken inspiration from the novel. I think at the start he was trying to just adapt it in some fashion, but before long it kinda became it's own thing with Inoue like making his ultimate grand "sports as way of discussing life and human beings" statement.
It´s significantly different, both regarding certain events and the actual tone and focus of Musashi´s journey
That's quite interesting. I wasn't expecting it to deviate to that extreme, especially not in regards to the philosophy of his journey. A little worrisome because I thoroughly enjoyed the tone and philosophical aspects of the novel but exciting in that it's new and I might even prefer this approach.
