I thought this was an excellent episode, and incredibly moving - I think it's the first time I've ever seen the 'expert' getting teary too, at Robert's reaction to the letter inviting Friedman to his grandparents wedding.
I can sometimes get a little bored when only 2 people are featured, but not in this episode - I wanted to know more and was pausing the TV to try & read the documents in full. I noticed that the asylum admission made reference to previous institutions, although these weren't mentioned.
In ways this was similar to the Boy George episode - relatively recent history and a tough watch at times, but very interesting and (thankfully) no OTT weeping from the 'celebrity'.
