"Hjärta av sten" (Heart of Stone) is definitely the worst Swedish movie I have seen in many years. We are used to the fact that Swedish crime fiction and movies have a remarkable international standard. Henning Mankell and Åke Edwardsson sell extraordinary well not even in Scandinavia, but in many other countries. Kjell Sundvalls movie "The Hunters" starring Rolf Lassgård and Lennart Jähkel has a well deserved IMDB-average of 7.3 points, I could name a lot of other examples, among them some features of the Beck-series with Peter Haber.
"Heart of stone" is the story of a Russian mafia killer who happens to be on the same plane to Stockholm as tough and brutal policeman Ronny Asplund (played by the otherwise brilliant actor Allan Svensson). A murder is committed by the Russian killer and thereafter we are witnessing an orgy of unmotivated violence among characters without any content. The dialogues are almost ridiculous; the decent colleague of inspector Asplund for instance always says something like "Please. Don't do that! No.", whenever Asplund is beating up or humiliating suspects involved.
Fortunately the film is over after 75 minutes, but even earlier you realize that every minute you spent on this was just a waste of time.
