Surviving British short subjects of the period seem to be primitively shot and executed. Part of the reason for this might have been lack of talent. World War One was going on, and fit young men were expected to be part of the effort -- hence, no doubt, the series, with its unnamed star in a sailor suit. Also, there wasn't much in the way of competition, with most of Europe engulfed in war and their film industries similarly ravaged.
