I love this show, but I agree that it's not for everyone. If you are looking for a tense, thrill a minute mystery, then you probably should move on. I love that kind of show, too, but I'm always up for something different.
Many reviewers dislike the asides by Annika and I respect their opinion. I happen to find them interesting and humorous, even if they slow the action a bit. I love her dry sense of humor. And I love the extra information imparted. If it's something I know little about - like the bridges in this episode and the Nordic myths in a previous one- I end up reading more about it afterwards. As far as the bridges are concerned, nowhere does Annika call the. Menai suspension bridge a truss bridge, as is stated in one of the "goofs." Morgan is referring to a part of the bridge she is building, and trusses are often a part of suspension bridges, though not the main means of support. The way the writers weave her little stories into both the case, her personal relationships, physically and symbolically is masterful.
The actors are all wonderful. So far I have seen nothing except outstanding performances. So why not a 10? For one, I think they're adding a little bit too much too soon for such short episodes. Mainly, I'm referring to the relationship between Morgan and Erin. I guess they needed somewhere for her to go, so Annika could have an overnight guest. And then there's DS Clarke's need to achieve. All of these have their place in the show, just not all at once. It doesn't leave much time for the case.
I am really looking forward to watching the last two episodes and am happy to hear there will be a second season.
