It's quite clearly based on "Driving Miss Daisy." Many of the episodes were homages to or take-offs of previous movies. I don't think anyone involve in QL would deny that.I have to agree with Samantha Beckett,this episode has always reminded me a little of Driving Miss Daisy.
All in all a great episode.
I love the tea scene. Both actors just nailed their respective positions. There was only so far Miss Melony was prepared to go, and Sam crossed the line. Her reaction was perfect.
