In fact, and with what is happening in this warlike and deadly world, I refused to watch Russian films, series and even read Russian novels, but I said to myself "let's not mix art with politics" and I started looking for this film-series whose trailer I saw on a rather run-down social network, and for me, it is an excellent series if we take into account its origin and acting experience. Both the decent and sometimes very good performances of the team, added to the subtitles (Spanish-Castilian: congratulations to the author of the translation), open our minds a little and we recognize that not everything is centered on three versions of FBI (USA), a failed Seal Team and supernumerary and boring products of the same origin plus the Tarantinos that flood our televisions with blood. My opinion: highly recommended.
