Because I like to think that if Sherlock happened in Finland, it’d be very similar to Raid. Which happens to be one of the best crime shows on TV ever and everyone should watch it. Although I suppose most of its laconic brilliance would get lost in translation. Like the iconic “Niinpä” the main character keeps repeating (it roughly translates as “yes” or “indeed” and kind of resembles Sherlock’s “Obviously.”).
And in case any Finns are wondering: I totally cast everyone based on appearance, rather than specific characteristics. And John is Uki because they have a very similar tastes in jumpers.
