I'm binge watching it to try and get me to stop doomscrolling. I'm on series 3. Sybil has just died and him in prison is going to duff someone up and kill them and go to the gallows I think (it's easily predictable). I'm very disappointed in it because it's so relentlessly miserable.
Does it get any better? It's like a cut price version of Upstairs Downstairs, which was at least well acted. I like the costumes though.
