Being an old fuddy duddy I was around in the seventies to read the James Clavell book Shogun. It was an acclaimed read, partly because the writing allowed it to explain patterns of thought behind decision making. It was followed by a film and a mini series which skimmed over the 1400 or so pages in the book.
I see FX have just released their attempt in the form of a 10 part series. I have watched the first episode and bearing in mind it is a long time ago now, seems to be sticking to the basic storyline. It might just be worth a look, especially if you have read the book!
