I was dismissive of Game of Thrones when it first came out, but after watching one or two episodes, I latched on to it because of the interesting plot twists, and especially the witty and sarcastic dialogue.
Riggs character, Olena Tyrell, was among the best in that regard.
Wow, I had not realized Diana Rigg was Olena Tyrell. You are right a terrific character. Hollywood screwed up G of T like they do everything. It was great series but the PC BS ruined it. By the end of season six women ran every kingdom, as if.
The dragons stole the show in GOT—even leftist PC couldn’t mess with that...

It was very well written, and I agree with you, her role and acting really shined.
