Of course it's just a subjective perception.
It is not like this.
Tatort = German
German films / series = boring
To put it bluntly, that's how it is
Not Nordic dark fantasy glorifying violence
Sometimes yes
So I love Tatort & DARK equally
Maybe because Tatort is a typical crime series that always runs like that.
It's a matter of taste. I think the series is mediocre. Entertaining yes, but just a rather 0/815 crime series with typical mistakes.
