To start off: Watch this movie and support the film by going to the cinema to watch it or rent it - you will not be disappointed! I highly recommend catching it in the cinema.
All in all, this is a great movie within the genre of Danish gang related crime films. It has great acting, amazing music and sound effect design, beautiful cinematography and a plot that works on so many levels I would have never expected! What I expected was 'John Wick' meets Danish gangsters, which wouldn't have been bad, but what I got was so much more. This movie manages to establish a truly sensible love/hate relationship through powerful scenes and dialogues and then continues to use this to its advantage. There are hints at many different things in the plot, which are a delight to discover and think about as afterthought.
I would say 10/10, but I am deducting a star for just a few handful of scenes and dialogues that seemed off and got the movie off to a bit of a slow start. Had they not been there, this movie would have been a perfect 10/10 and maybe the best of its kind within the genre from Denmark of all time. It arguably still is.
TLDR; 'Underverden' is a classic revenge movie, as summarized in the plot description, but it is also much, much more than that!
