I had great hopes for this series after first meeting Sister Boniface in the Father Brown series.
However, I find that the writer(s) severely underutilize the supporting cast, especially the African policemen who had hoped to join the Met in London but got stuck in Great Slaughter. No subplots or deeper character elements have been written for him. Why is he even on the case?
The young white (male) inspector is just a hapless pretty face.
The only supporting character (and we are a third of the way into Season 2) is the female character, Officer Button, whose compassion as well as courage have been allowed to shine.
Unlike in Father Brown, where every single supporting character has a distinct personality and you can reliably predict how they will feel in any given situation, Sr Boniface's colleagues are primarily a blank.
With the exit of the vivacious and flighty newspaper reporter, the spark has almost expired.
Very disappointing.
