Spoiler alert!
5 stars for the scenery/cinematography, and 2 stars for the struggling plot/writing. 4 stars for actors dealing with the script (btw, why kill off one of the most interesting characters in the first half hour?).
Major belief suspension required as the episodes move along - Karla, you're not really that thick! Hannis, you're way too smart for a cack-handed plot like this. I was seriously worried that it wouldn't be solved before Anita went on maternity leave as she seemed to be carrying the case for the police. And what's with introducing the villains in the final 20 minutes of the series (well, one of them)?
I wouldn't be surprised to discover that Ragnar's call with the new mysterious "big(ger) boss" came from Tony Soprano (too late, but what the heck).
Hey, don't worry, just get some sweets, a glass of wine and enjoy the scenery. It's still a good night in.
