I finally gave in and watched it after multiple independent recommendations from people who had strong educated opinions on quality nuanced literature and media. The last series sort of declined a bit, but overall I was in no way disappointed. It was exceptionally well done, and importantly for me, not too watered down with tired tropes, stereotyped single dimensional characters, painfully predictable plots and neatly tidied moral threads.
I mean, there were definitely some, but, it's TV. It holds up extremely well even with age.
