Mihail Bilalov (Djaro) is the PERFECT actor for a mafia boss. His looks, his manners, his form of speech, there's nothing wrong with how he portrays his character. He's just incredible. So is the rest of the casting crew (with few exceptions). I'm happy that the Bulgarian taxpayer's money are finally going into something worth watching. In the series there are a lot of Bulgarian inside jokes, so I assume it would be slightly harder for international viewers to understand the jokes from time to time. Otherwise the show may not be introducing new things to the genre (is that even possible nowadays?), but it's perfecting on the most important parts. TV series like Breaking Bad have much more higher budgets and their production quality is way better, but Pod Prikritie (Undercover) is still a worthy opponent.
