I think programmes like these are very good. Most seem a lot better than similar UK series. The Bridge, Borgen and other Scandinavian serials do have to be concentrated on, but the acting makes this worthwhile. I also liked Spiral, the French crime series which was very gritty, and Montalbano.
We started watching the first episode of what was supposed to be another Scandinavian series about two or three weeks ago. I can't remember on which channel it was on, but it was set in some Arctic region where everyone spoke English in various accents. It was not until we saw a policeman with a badge saying 'Polis' that we realised that this was supposed to be Sweden, but was entirely in English. As soon as we realised that, we gave up on what may have been a reasonable story if it had been in the real language. Presumably for those who do not, or cannot read subtitles.
