Set soon after the Jack the Ripper murders, Ripper street is a solid crime drama with decent characters. After 3 episodes it seems to be finding its feet. Detective Inspector Reid is a smart, middle class man with a backstory involving his family and events during the war. Sargent Drake is a local police - more of a blunt instrument right now.
They try to emulate the paranoia of the time - if a woman turns up dead IT COULD BE THE RIPPER!!!. While Inspector Reid is more pragmatic about each case.
They will probably move away from this paranoia and it should become a solid procedural show.
Compared to Copper (co produced by the BBC), Ripper Street is a lot better, in every department
