I've read the book at least three times, and I'm really enjoying the show so far. I was however very disappointed in a change they made to a scene I was looking forward to in Episode 2. I get it, TV adaptations have to tweak the script, shuffle around characters, play with the sequence of events, and so on. That's all part of the game. But what they shouldn't do is mess with the stuff that's at the very heart of the book, the stuff that really matters to the story.
In the book, there's this powerful moment when Toranaga meets Blackthorne. Toranaga says, “There are no ‘mitigating circumstances’ when it comes to rebellion against a sovereign lord.” And then Blackthorne fires back with, “Unless you win.” That exchange is gold. It shows why Blackthorne and Toranaga click. It's about how Toranaga, even though he's from this super strict Japanese society, is always ready to throw the rulebook out the window when necessary. He gets that history is penned by those who come out on top, and that power is what makes the rules.
But in the show? They water it down to Toranaga saying, "You have too many enemies. You cannot win," and Blackthorne replying, "unless I win." I mean, come on! Why? Why strip away the brilliance of their original exchange?
I'm just baffled and a bit annoyed, to be honest. Lol, I just don't see the point of making that change.
