You might enjoy this movie if you haven't seen the swedish originals and like James Bond... but if you have seen them then...
This is a perfect example of how to ruin brilliant and subtle characters, (Lisbeth Salander and Mikael Blomkvist of the original swedish movies) and deep moving stories with the Hollywood, dumb-down approach to story, writing and acting.
Original story creator Stieg Larsson must be regretting the money he took to give control of his creation to such unimaginative writers. Lisbeth is now a James Bond style action hero-hacker who literally jeopardises the world and is then on a mission to save it. The smart genius engages in uncharacteristically dumb behaviour just to service the plot.
features ducatis, lamborghinis, familial arch-enemies dressed in red, nuclear missiles, lone NSA secret agents etc etc blah blah.
