Good start to the new series.  To replace the entire main cast and still have the cast gel as well as the new cast are doing shows some pretty good writing and a good cast.  Can't remember the name of the actor playing the devil, but he's popped up in lots of dramas, "Whitechapple" being the last one I recall, and always plays his characters well.

BTW, Ripper Street is an excellent series.  Going to start a thread about it!

No. I'm avoiding it as I watched a bit of Series One and have not seen any since. Planning to buy the blu-ray box set and do the whole lot in one go. My last and only post as I don't need any spoilers
