To understand how this is different from Fincher's version look no further than some road signs in this film - you can clearly see that they are not in swedish (Fincher would never let something like that happen, and that applies not only to signs, but to everything else).
Was ready to hate it, but it was not THAT bad - Claire Foy is a decent Lisbeth and grows on you, and there's a cool Lakeith Stanfield here, which is always a bonus. The less said about the Blumkvist, the better.
