Quite liked the Hollywood version of this, more because of the storyline and the scenery than Al Pacino's sleep deprived cop but am going through a scandinavian film phase at the moment so had to give this a try - and I'm so glad I did. I found it a much superior version, gritty, moody, cold, intriguing, and best of all, it didn't have Robin Williams in it as a creepy comedy villain. Felt I had to work a lot harder with this version to understand what was driving the characters and muse over the justification or otherwise for their actions but in doing so, I got much more satisfaction out of it. By contrast, the Hollywood version encourages lazy passive viewing, waiting to be spoonfed your next opinion. Interesting that the scene with the dog is missing from the US version - clearly that would be a step beyond the pale for Al Pacino!
