I don't speak Danish. It sounds like superspeed oddly-pronounced Swedish, but after watching a stack of episodes I've come to enjoy the language, the way it sounds and even learnt some (only because I can understand some words through my knowledge of German and Swedish). I watched a lot of Wallander (both the Swedish versions), and this reminds me of it. I'd love to see some Norwegian, Finnish and Icelandic TV to complete the Scandinavian set. Another Danish series that I'm just about to watch is 'Borgen', which is like the KIlling's political side (which I rather enjoy). Maybe I should start learning Danish..
