This was fun to watch; an enjoyable time-travel science fiction story. The acting and plot line let me suspend any disbelief up until the end.
I would have given it 5 stars except that the 8th episode had some jarring items.
A crippled woman, found nude in an alley, was somehow placed in a jail cell in the men's section of a prison.
A woman in 2023 was using a record player with a 78 RPM setting.
The elimination of a powerful secret organization, which had seized control of the London police force, had absolutely no impact in 1941 or 2023.
