Many people cleverer than I have described it as the finest TV drama ever made, I wouldn't disagree. Needs some commitment as it starts slowly and lasts 48 hours. But I'm rewatching it and will probably watch it a few more times, it's that good.
I like them both, two high achievers, very bright, understated, ever so slightly charismatic, blue an emblematic colour for each of them.
Have they ever been seen in the same room I wonder?
Any other BHA lookalikeys?
