Wow, saw this last night & ended up loving it - unexpected because I'm a fan of the Swedish versions. I thought it would feel inauthentic and it some ways it did (the accents, ugh) but otherwise it was surprisingly loyal to the book. I can't pick my favorite Salander, though. Both actresses were perfect in their own way. I was pleasantly surprised by Daniel Craig - I only know him as Bond.
The opening sequence - it was overly stylistic but omg, loved the Immigrant Song remake. I noticed Trent Reznor did the music.
