I tackled this book after putting it off forever. I'm in Sweden and this trilogy is HUGE. And, well, I have a tendency, for some reason, not to I 'get' popular books.
This one is no exception to my trend, I didn't get it at all. I did read it in the original Swedish, as a few English speaking friends tried it and didn't like it and suggested translation errors.
I made it through 100 pages and, to my surprise, found it way too slow going to get my attention at all. Usually with mainstream thrillers I find them a fast read,but flat in terms of characters.
My main issue was that every new character was introduced with endless and seemingly useless backstory. When I asked a few friends if I should continue reading, they said 'oh, the next chapter he spends most of his time introducing a whole slew of characters' so I gave up.
One person I know suggested this book had limited editing because the author died before they could make all the changes. Don't know if there is any truth to that, but that was how it felt to me.
Different strokes for different folks, but as the book is so loved here, I usually act as if I never read it if someone asks. And honestly, given that I only read 100 pages, I guess I didn't.
