A satisfying binge. I highly recommend watching this while NOT folding the laundry. That way you can be present for the entire story and enjoy the excellent acting and well-told, suspenseful murder mystery.
What another reviewer identifies as "tropes" were not actually dramatized as such -- the female detective did not get more involved or emotional than you would expect for someone searching for her missing daughter (filmmakers were actually quite restrained in how they presented this). Also, there weren't any of the stereotypical ego clashes between the outsider and the insiders on the police force. The new captain did indeed recently move to town and only the first episode depicted the awkwardness of this dynamic, and what was shown would be natural to this plot detail. It wasn't an ongoing part of the story in the way it would be on a prime time American drama. In fact, I enjoyed that there wasn't any development of the stereotypical "clash" between the new captain and his staff (that would have been a trope).
I would say this show is on par with Broadchurch in terms of acting and production quality but with a slightly more simplistic and traditional story and resolution. Most implausibilities had decent explanations and probably more so than do the typical crime drama. The acting and unfolding of the story were nuanced, and restraint was used with plot details that could have become cliche.
I especially enjoyed the story's two intertwined layers - the search for the missing girls and the teacher's search for her identity.
