I remember this being on TV, and that there was some controversy at the time, but I never watched it and I'd entirely forgotten about its existence.
Out of curiosity I thought I'd watch a bit of it - and I was hooked! I ended up watching both this episode and the next one, and really enjoyed them. I'm looking forward to watching the whole series if I can find the time.
Frank Finlay was quite a mesmerising character, and the acting generally was superb. It reminded me of the old `Play for Today' series, which is high praise indeed.
The very obvious sexual attraction between Finlay and his (admittedly gorgeous) daughter was also brilliantly captured, and I'm sure it would be just as controversial today - in fact in the present climate it would probably never have been made.
It's also interesting that the scene when Susan Penhaligon gets hit by her boyfriend would probably have caused far less controversy in 1976 than it would these days - giving `the wife' the odd slap was, shockingly in retrospect, considered relatively normal back then.
So thank you for bringing it to my attention - and for giving me yet another excuse to waste time that should be spent productively!
