"Just please, the producers: a trifle more comedy, and a little less darkness."
I do agree that this program can be less gory and gruesome than it is. But I think it would be a disaster if the producers decided to bizarrely make Ripper Street more comedic and less dark. Tracking down hardened criminals and ruffians in the late 19th century should not, for the most part, be done in a lighthearted way. There already is a program out there which does what you wish and which also takes place in the late 19th century but in Canada instead of England and that would be the program called Murdoch. For the most part Murdoch succeeds in being a drama and [somewhat] a comedy. But a program like Ripper Street is better suited, in my opinion, in the way it treats its subject and its characters [though, again, the overt violence could be toned down a bit] rather than trying to win over its audience with belly laughs.
