The story is a bit jumbled, but Mads performance outshines any issues I have with the film.  This one is definitely worth watching.
 
FUN FACT:  According to Mads Mikkelsen, there was not any alcohol involved on shooting days. Yet off set, there was some experimentation on what specifically would happen at 0.05%, 0.08%... There was even a "little boot camp" to monitor how speech and movements changed. But for the "next crazy Charlie Chaplin level" the team watched a lot of YouTube videos.
