Did the Rank organization have hopes of competing with the Huggetts family series when they went into production with this one? It's clearly based on a two-act family drama about a family where the children are growing up, the acts separated by a couple of years, and with minimal expansion to account for the fact that not everything has to happen on the same set: a couple of shots in the street and one upstairs manages that.
Also, the Hapgood family is clearly middle class. All the men have office jobs or are in public school or are being sent to Africa by the firms. It's bland and well performed, directed and shot and a good time-waster by all concerned. If there is nothing that stands out as surprisingly good, there's nothing to complain about this slightly old-fashioned storm-in-a-teapot movie.
