I'm a child of the 60's (grew up in the 70s). Whilst I recognise some of the commonplace activities of the 70s in this series - like the blase, pre-"Just Say No..." attitude to taking drugs - none of the storyline was very convincing, despite the period outfits and (peeling) wallpaper.
Furthermore, I'm not sure who this was aimed at and what it was trying to say - I just didn't get it (apart from the obvious swinging couples, friendship jealousies etc.). In fact, I didn't have to squint much to see the 3D image in this 2D production: the whole thing had a feel of bow-chick-a-wow-wow 70s sleazy, cheesy, corny porn what with the moustaches and the innuendo-laden attitudes of women which used to be considered sexy at the time.
But the main reason I chose to watch this was because of Jack Davenport who I think is usually a very good actor what with his sensitivity to and intuition into the roles he gets landed with. Not so this time round, though. He felt raw and uncomfortable in this role, and his "American" accent didn't do that any favours. One could see his usual deep, charming, endearing "British-ness" coming through in what was, essentially, the shallow character of Bruce. Definitely a mis-cast here.
I can see why a second season wasn't met with any enthusiasm. Sorry...
