They had about ten minutes picking it apart on their Wednesday podcast. Basically, too much love for the Old Etonians (which is kind funny coming from two quite poncy Brits), too much romanticizing life in mining towns, and crap football scenes.
Lazy writing (it seems everyone in the British Isles knows everyone, even in 1879), the story seems rushed and the soccer action scenes are indeed crap.
and enjoying it thus far.
You definitely get the Downton vibe.
