I've seen the Swedish trilogy, and read the first book. They're OK. I was actually disappointed that David was doing this film, as I figured I'd had enough of Lisbeth. I'll say that Fincher's version is the best of the group, and I'm actually looking forward to the next two.

Trent's score was amazing too; really complimented the film, just as he did with The Social Network. I think David Fincher has found his Danny Elfman.
