There are quite a few, in my most humble opinion!
For starters:
New Tricks. Way past its sell by date for me.
Still open all hours. Should have shut them when Ronnie Barker left.
Death in Paradise. Despite the endearing Kris Marshall
Call the midwife. Hackneyed in Hackney.. or caputneyed in Putney?
Any other suggestions?
What were the first ever records that you bought and when?
Parents-in-Law. What do/did you call them?
