So, with less than two weeks to go until the watch begins, thought I'd just make a few points about the show that people should keep in mind before watching it:
Subtitles If you don't live in the UK and don't watch that many UK shows, I'd strongly suggest making sure that the copy of the eps you've got has optional subtitles, at least. They won't be needed all the time, but the northern accent used in the show really is thick, at times. I'd say they're as strong as some of the southern accents used in Deadwood. Definitely something to keep in mind, I think.
Give it ten minutes If you have no clue what the show is about, the first ten minutes might come across as boring, at first. Stick with it past those first few minutes, though, and hopefully you'll find it gets a lot more interesting. Don't worry. You'll know when it starts getting interesting when you see it.
And, most important of all: Be sure you're watching the good version I cannot stress this enough (especially since someone else heard about how much I loved the show and started watching the remake by mistake). If the version you're watching is set in New York and stars Kietel, ignore that. It's the 2006 UK version starring John Simm and Philip Glenister you'll be after.
Ok, hopefully, that's all you need. I was considering making a teaser trailer based on The Girl With The Dragon Tattoo teaser trailer, but then decided against it. (For anyone wondering why, here's a trailer I caught for the show when it was first shown in the UK (first episode spoilers for anyone who wants to be left in the dark about what it's about, btw):
