I liked Salander. The original Swedish films portray her as slightly less cool and able than the American version , but in the original she comes over more unintentionally but genuinely cool and has an air of innocence even though she has faced up to and and had to deal with terrible things. In the book, she is described as repaying every kindness shown to her in full. She genuinely cares for her first probation officer after he has a stroke ,and she visits her mom in a hospital . Much of the story centres around her weighing up Blomkvist and the friendship and trust that evolves.
Stig Larsson , the author, was an interesting man. He was in the Swedish army and served in Eritrea training women fighters to use rocket propelled grenades. I think his respect for women is evident in the books he wrote. They are not meant to be high literature, but crackingly good stories in which the characters are either evil men ( and women) or compassionate and strong. There are many ways to watch the films or read the books , one is to see the baddies as sociopaths (the original title was Men Who Hate Women) Vs the good guys , and it is seen and made sense of primarily through Salander who was intended by Larsson to have some strong Asperger's characteristics and traits.
Her half brother is a total murderous sociopath ( has nerve damage and feels no pain) and when I saw the second film I wondered if Larsson was alluding to Hans Aspergrer's diagnostic separation of us from the sociopaths back in the early 1940's.
I also think if the trilogy is about anything , it's justice .
