I find it almost impossible to watch this right through, so nostalgic is it of a way of life virtually gone now. The blend of professional actors with, presumably, real-life characters works well. There's nothing really to fault-photography is very good and sharp; music appropriate; lots of familiar faces-e.g. Megs Jenkins, a young Harry Fowler...
Couple this with "The Song of the Road" (1937), which is about the replacement of horses on farms, and you have a pretty good depiction of life in England before and after the War. One critic summed up the 1937 film as "..a sentimental, idealised account of a country at peace with itself". It's not that simple of course, but there are plenty of documentaries about analysing the harder edge of those times.
Enjoy these films for what they are-wonderful depictions made with feeling, and valuable social documents.
