Went to see the Hollywood version of The Girl With the Dragon Tattoo last night. I saw the original Swedish version a year or so back, and I think I prefer this new one - it's better paced and better filmed (though there are a number of scenes which might as well be shot-for-shot remakes of scenes in the Swedish version) and the fact that it's in English, so has no need for the painfully badly-written subtitles, helps. I don't think it's quite as graphic as the Swedish version, though.
Whether you've read the books or not, or if you've seen the Swedish film, I'd recommend this to anyone.
