I see loads of women and no men reading this on the train whilst commuting but thought I'd give the series a go as it's obviously popular. Stuff appearances, I'm buying the books now as this series is absolutely amazing!
Urbanlake mentioned the Blu Ray image quality is grainy and I agree that for this format it's unusual, however I think it is done purposely as many scenes are of a standard I expect from Blu Ray and overall it adds to the gritty feel and nature of the story.
The plot contains more twists and turns than a screwed up ball of wool and is utterly engrossing - heck even my other half, who can't sit still - EVER, was immobile for two, three hour sittings mesmerised by the story. Watch it in Swedish or in dubbed English, it doesn't matter either way, you'll be hooked.
