Shogun

Many years ago, certainly over 55 years, I read a book called Shogun by James Clavell.
In the late 70's it was made for TV with Richard Chamberlain (Dr Kildare in another TV series, bet that took some of you back in time). I remember seeing it but not sure if I caught all of it.
And now I find it's on Disney+ as a mini series, six episodes. I don't remember much about the TV series but remembering the book I just have to watch this version. It seems to be following the book accurately as far as I remember.
Excuse me, I'm going back to it now, I'm on episode 4!
