Henrik Vanger (Christopher Plummer) wants to solve the 40 year old disappearance/murder of his 16 year old niece. He enlists the help of investigative reporter Mikael Blomkvist (Daniel Craig) who thinks he is on to something. He needs an assistant and employs the talents of Lisbeth Salander (Rooney Mara) in the title role. Lisabeth is a savvy psychotic bisexual computer hacker/investigator who provides us with a dark bizarre subplot.
During the investigation they uncover hints that point to a serial killer, who kills Jewish women based on quotes from Leviticus. The mystery isn't too hard to figure out with the numerous clues that they give you. The movie is best when Rooney Mara is on the screen.
As good as you're going to get in a single movie. True to Larsson's story, but very condensed to fit the time frame. The ITV extended and dubbed version provides the best rendition of the trilogy, but I continue to like this US version as well.
