The FX / Hulu version of Shogun concluded this week.
I haven't read the book. I don't remember much of the Richard Chamberlain version, which is only available on DVD currently.
This was a really good mini-series. Excellent visuals, costumes, fight scenes, story lines. Hulu also had a podcast for each episode featuring writers, directors, and cast, which helped to explain a lot of the historical context.
