WORTH-IT

BollyMeter7.0/10Series 3 maintained the format through James Norton's penultimate run as Sidney Chambers; the writing began preparing for a lead transition without sacrificing the Keating-Chambers dynamic.

What BollyAI Thinks

Series 3 aired in April 2017 and ran through May. James Norton continued as the clerical investigator while the series began the groundwork for a succession storyline - Sidney Chambers would not remain at the centre of Grantchester indefinitely. The 1960s setting allowed the production to stretch into a period of social upheaval that gave the crimes more political texture. Robson Green's Detective Inspector Keating remained the show's most reliable emotional anchor, his pragmatic police work a necessary counterweight to the vicar's idealism.
