I saw the devil - 3.5 stars
I haven't seen anything as gruesome as this film, yet. Both the main characters were awesome in their respective roles. The only reason why I've given it just 3.5 is the movie length. I felt it could've easily been at least 20 minutes shorter (especially towards the middle of the film where it seemed like the same scene occuring over and over again), without the plot losing direction. A simple revenge story, but shown in an unimaginable way.
Watch the unrated version if you can. Watch it alone.
