I haven't re-read it in about twenty years either but I did watch the TV series. I feel the same about having read it as dystopian futurisitic SF on an alternate timeline when I was in my twenties and now, thanks to world events and my own experiences, finding it far more realistic.

I didn't watch the second TV series because I didn't think I could cope with more but I have it recorded. At the moment I am listening to The Testaments as Radio 4's book at bedtime and I now want to watch the second TV series after that once I've had the authorial version.
