thanks for the comments so far everyone.
I guess we're all giving our age away here simply by voting on this one!!! Anyone under 35 probably wouldn't even be in a position to vote here...
For myself, I am utterly alienated by modern commercial television and therefore don't watch any apart from sporting events. Perhaps I have a romantic, whimsical, slightly nostalgiic view of what tv should be like, but, as I was growing up through the 1970's and early 80's, these programmes really set the bar high. And there were a whole swag of them in these years; we need a couple more polls to do them all justice...other highlights for me were The Love Boat; Good Times; Little House on the Prairie; MASH; Eight is Enough; The Muppet Show; Fawlty Towers etc etc.
Through the late 80's and into the 90's it was Moonlighting and LA Law, but really, nothing has grabbed me since then. The adds are enough to make me cringe. I find modern tv way too in your face, violent, amoral (and just blatantly immoral - satanic really) - even comedy has a bitter undertone and a nasty, cynical edge to it that I find repellent. The 70's really was the high water mark for tv entertainment, with just the right mix of humour, sassiness and family friendly values. These days even "kids" shows have adult content as far as I'm concerned.
Anyway, that's my 2cents worth.
As a parting shot, I probably should say that tv really is only a reflection of the culture out of which it is produced. What saddens me most about that though, is to think what has happenned to our society in the intervening 30 years since these shows were made. I miss the days when life was simpler. But hey, my favourite colours are still orange and brown so what can I say!
