It's Charles Critchton's second movie as a director, and his training as an editor contributes to the brevity of the piece. Mustn't let the audience grow bored with lectures! Although there are professional actors in the movie, particularly Jenny Laird as the ingenue, there's a handsome authenticity to the movie. The characters all seem genuine.
