Everyone in the series seems to be nice and pleasant. Even the murderers don't seem to be truly evil. There's nothing in Viveca Sten's universe that offends. People we know barely nothing about are the ones who die and subsequent crimes are always attempted murders of characters we've got to know a bit about and are generally saved from death in the nick of time.
There are back stories to the main characters whose lives mesh seamlessly with each other although true romance is always an on/off affair. They have their problems, of course, but these don't generally interfere with the denouement of the plots.
The setting in the archipelago is stunning. I've only been there a couple of times and the series makes me want to go back again one day. It's all so perfect just as Sweden is portrayed abroad.
I've seen all seven seasons and am eagerly awaiting an eighth. It's absolutely not Scandi Noir, more Rosemary and Thyme, but that's not a reason to be critical - the genres are different, that's all. I like them both and this series is a great example of an easy watch that holds the attention.
