I saw it at an (almost empty, can you believe it, half a mile from SB's own home ... !) screening in North London. I loved it - SB was on great if familiar form and suggested lots of emotional depths behind a gritty northern exterior etc etc etc. The cinematography was particularly impressive and of course, as there always is in anything set in the 19th century, a great deal of FOG. The only thing that niggled me was that it was so obviously not filmed anywhere near the Thames or London. The colour of the stone, the countryside, the river, the light ...even if I hadn't known it was filmed in northern Ireland, it would have seemed that everything about the landscape was wrong.
But hey ho ... willing suspension of disbelief and all that. I'll certainly be tuning in, if I can find it, to episode 2.
