I watched all of the series and it seems they all have a great quality that stands up the Hammer name.
A lot can be learned from watching both the characters and the set decorations used during this series.
Episode 7 really stands out as the one I would watch more than once.
Episode 9 would be my second choice.
I only wish there were a few more that I could watch as 13 seems to be a bit short of a run.
