The Girl Who Played With Fire centers around journalist Blomkvist (Nyqvist) and computer hacker Salander (Rapace). When Salander is suspected in a triple murder, Blomkvist attempts to get to the bottom of it. And that's about it for the plot. The Girl Who Played With Fire is, like almost all sequels, not nearly as good as the first one. Part of it is the writing (this being the middle of a trilogy) and part of it is the directing (this being a different director). The movie as a whole just doesn't seem as tight or as meaningful. The cinematography feels video-esque and the atmosphere less moody. Unnecessary scenes are retained and almost emphasized. Despite that, it's still a good movie. There were tense moments where the lives of people you cared about hung in the balance. There was fascinating depth added to Salander's originally superficial character. But overall, it feels as if there just wasn't as much care put into it or as much detail paid attention to.
