Just watched this other night for the first time...partially because I really enjoyed the original and most times do not like remakes. While I did enjoy this one to an extent, I found some irritating flaws about it. (Note, do not read on if you've not seen the original, the remake or read the book unless you don't mind spoilers that is lol).
1. Why on earth would they change how they found Harriet? The original did it correctly, yet the remake changed it from how it was in the book and the original...just dumb if you ask me.
2. I and my husband preferred the way Noomi Rapace portrayed Lisbeth Salandar to the way Rooney Mara did...we both felt Rooney a poor actress in this film.
3. The book describes Lisbeth as pretty, and while Rooney Mara in her own right is pretty, for some reason the film makers or make up artists (whoever you choose to blame) made her look rather unattractive and no it was not the hair that made her look so (in fact at the end when she had the blonde wig on, she finally did look pretty, but I put that down to different makeup as well).
4. We both think that Michael Nyqvist did a better job of playing Mikael Blomkvist than Daniel Craig did as well...but then again, we were listening to an English dub over, however the expressions on the faces certainly helped, Craig and Mara seemed a bit wooden...granted Craig's been good in other things (and I am not saying anything Bond, because I still think he does NOT fit James Bond or Ian Fleming's description of him :P).
These are only hubby's and my thoughts on the film at any rate...I did enjoy it to a certain extent...but not entirely certain whether I will watch the other two if they do remake those.
