I don't want to say anything bad about a Humphrey Jennings movie. After all, the man made some of the best propaganda shorts of the Second World War and his common-man-doing-his-common-job documentary style is very telling. Also this movie does show a wry sense of humor with a mild capper joke at the end.However, the movie is about how a boy in Manchester mails a penny postcard to his aunt on a farm in Sussex and how it gets there in less than a day. It's about the dull routine of sorting and things being carried on trains and a man putting down his bicycle to walk over a hill. It's about logistics, and while good logistics is an important economic force for shaping our world, it's still a dull subject. Even if there is some nice scenery on the way.
