I've just finished Haven. It makes me want to visit Nova Scotia. Not to mention the more shallow reasons for watching it (for example). I'm going through withdrawal so need to watch the gag reels and other promotional stuff.
I'm also enjoying a 4-part detective series called "Hinterland". From the name, you wouldn't realise that it's set in Aberystwyth (West Wales) and the characters speak a mix of english and welsh (with subtitles). Welsh is used for greetings, casual conversations and such but for anything important, they switch to english. What I like about it is that it has regular people doing bad things under difficult circumstances rather than psychopaths.
