Jane Seymour was much better. Byron was almost as annoying when he was Jan-Michael Vincent... I did think both actors for Aaron Jastrow were very good.
I also watched these a couple of weeks ago. Just timeless and fabulous storytelling.
Didn't care for Gielgud's private life, but his portrayal of Aaron Jastrow was one of the greatest performances I'd ever seen. The scene were he gives the sermon in Thereisienstadt about Job "The Stinking Jew" is one of the most powerful things you'll ever see.
Yes, great watches ..I adimit I binge watched the enire series.
