The movie does a poor job of showing her motivations and of actually making the story make sense. I don't see how people could understand it without reading the book first.JimB said:I think it was MovieBob who said Lisbeth Salander is supposed to be some kind of fantasy girl; a perfect woman for the author to masturbate to. This kind of revenge fantasy fits in pretty well with that theory.
Essentially, Salander has been dependent on someone else for her entire life. She has a very dark personality and so she was an outcast for most of her life. She saw many injustices throughout it because of people making judgments just on her looks and on the looks of the people she hung out with. Because of this, she became distrustful towards pretty much everyone (including the police). The only person she trusted was her previous guardian. When he died, she had no one to trust. When her new guardian starts raping her, she considers going to the police but because of her past experiences, she doesn't believe that they could help her. She thinks they might even side against her. So she does the only thing she can think of. She gets video evidence and then makes death threats to her new guardian. To insure that he knows she's serious, she sexually abuses him and then tattoos him. Was she right to do this? No, this was very wrong but it was what she knew.
I don't see how this makes her sound like "a fantasy woman who is perfect for the author to masturbate to". It makes her sound like a complex and tragic character who is emotionally disturbed. Dismissing her as some sick fantasy of the author is just ridiculous.
