After two episodes my conclusion is - piss poor.
A decent adventure drama needs pithy dialouge, gripping plot lines, exhilirating action, dramatic tension, engaging characters and convincing performances.
This has none of them. as well as the absence of these essentials it hsas extr bad points - the half baked philosophical musings, Robins pomposity, Keith Allen's pantomine performance, lack of any convincing historical detail and the complete absence of the depiciton of any actual violence - leaving us to 'thrill' to bloodless fight scenes that look like playground wrestling.
Also its way to clean looking - no boils or pustules and a marked absence grusome dertimitological afflictions generally.
And I really wanted to like it too.
