The movie shows how modern authority figures gained their power and capital. A lot of them came from not so clean jobs and the movies shows details of that.
Two guys - Simon (Duzhev) and Sergey (Aleksey Panin) - are working for a local mobster (Mikhalkov) as negotiators (extortion specialists actually) and killers. They are not brain surgeons and are quick to pull out a gun, which always puts them in different awkward situations. Considering there are competitors such as crooked cop, local dumb criminals and other low-life element, Simon and Sergey are in for a fun ride... Expect lot of gunshots and a sea of blood.
The movie has gathered a great number of Russian cinema stars even in episodic roles (Andrey Panin is an architect, Andrey Krasko is an unlucky neighbor, Dmitriy Pevtzov is a drug-dealing lawyer, etc.), which makes the movie so much fun to watch. Under a virtuoso management of the director Aleksey Balaganov all characters are simply dumb and extremely standardized, which makes it look like a joke.
Just like Guy Ritchie's movies this one can not really be taken too seriously. On the other hand it's too much dark humor and too much blood to be considered a comedy.
Just keep in mind that it is a true biography of some today's Russian politicians. Perhaps, that will leave you thinking.
p.s. "The Russian Ethiopian" is absolutely hilarious!
