I don't know whether Follyfoot was ever repeated: for me it's a creature of the 1970s, which happened on weekend teatimes. I watched Follyfoot of course, because it had horses in it, but I never liked it, or the books, as much as Monica Dickens' World's End series.
It was the hopelessness of some of the story lines, I think, that got me. It depressed me, and I like a bit of fight with my stories. Dora in particular I found difficult, though I suppose the desperate fight the Farm had to stay afloat, and its awful cases were at least realistic.
When I was doing the Monica Dickens page for the website, I came across this site: whose owners obviously didn't suffer from my dislike! So, if you are at all interested in Follyfoot, this really is the site for you.
I always thought the World's End series would make a good television series. It was one of my absolute favourites as a child. I cherished my Piccolo paperbacks, and I still have them (have not yet managed to upgrade them to beautiful firsts). The difference between the two series for me was that however awful life at World's End got (and things did get extremely sticky at times) things usually worked out, even if it wasn't as you expected, or even wanted. I loved Carrie and Lester, and her horse John, and the way she would ride him amongst the stars at night. And I liked the cast of adult characters; more or less concerned, and the frightful aunt tiptoeing amongst the animals trying not to touch them.
