DOTTY OVER-THE-HILL eponymous medieval meddler BARNARD HUGHES helps/hinders dopey teen CLARK BRANDON in meddlesome sitcommery ways. “Working in a garage isn’t exactly Camelot; now they tell me I need an apprentice!” That was the “sit”, right there. Mr Merlin accessed own magic room by tapping on the wall of his house, which would open up a doorway and staircase leading upwards to his laboratory. There was an owl, and the lovely Alexandra, a blonde spirit. But still no sign of the “com”.
