I usually only watch series where at least one person is likely to be murdered, but although I started off loving Downton Abbey I got very bored with it by the time it was turned into a convalescent home during the war. I started watching Call the Midwife one day and was hooked, but again, lost interest a series or two back and I suppose for me, that's a sign that things need changing, as I no longer look forward to them. I realise that others do still love them, and the americans adore them and bring in a fortune as a result, but I just find that I have less and less to watch on tv as a result of finding the programmes past their sell-by date.
