After watching the desperate Martin Freeman in each one of the Responder episodes, I felt wrung out and exhausted. The intensity of the drama and the emotional trauma felt by the characters was amazing. Setting off to be a model officer, Rachel has realism beaten into her on the street and at home as it turned our. Chris Carson was there to catch her too, despite his own circumstances.
Evert aspect of his ruined life is exposed in the story.
No less desperate are the drug addled anti heroes.
