Not only was this a favourite of my own childhood in the 60s and 70s, but the video edition has been a favourite for both of my own children.
Oliver Postgate's ear for dialogue and his off-beat, self-deprecating humour make this a wonderfully engaging portrait of the "top left-hand corner of Wales".
This is a very gentle, reassuring world, ideal for very small children (from the age of about two upwards) but with enough in it to endear it to adults even after they know it off by heart. AND it runs for three whole hours -- not just great value for money, but suitable for plonking a wakeful toddler in front of it while you go back to sleep on the sofa!
