As a big fan of the Tatort phenomenon, this episode was deeply disappointing. The story is filled with senseless violence and abundance of depressed (and depressing) characters. The Kommisar team Borowski and Brandt have never been less appealing. Borowski goes over and beyond his usual narcissist and sexist behavior, even lowering himself to calling his colleague a "stupid cow" when they disagreed about a point of procedure. Kommissar Brandt is struggling with a newly diagnosed and very serious chronic illness, frequently taking in pills. Borowski is depressed because apparently his wife and teenage daughter have exited his life, and is desperately seeking female companionship. --
The episode title is derived from the annual festivities at the "Kieler Woche", where extended carnival-like partying culminates in an impressive "parade" of classic ships and sail boats. A few brief scenes show Borowski in the company of an Asian immigrant waitress who made it clear that she was "legally in the country and in no need of a native born husband". --
A major contributor to my low rating for this episode is the repulsiveness of the "killer", who seemingly murdered repeatedly without a motive. Other minor players are of similar debased character, making it difficult to watch the entire film, much less be entertained by it. - I've seen the Tatort Team from Kiel in many other episodes, some of which I rank among my favorites. "Borowski und das Fest des Nordens", however is very far from the mark. Avoid this one, it's not worth your time!
