I think the storyline has dragged and there are a lot of holes in the story but it's still a fantastic watch that has me gripped and desperate to see the next episode.
There have been some really gripping foreign crime fiction series - the Bridge (Danish/Swedish) being my favourite. But because you read it rather than listen, I think bad acting/plot flaws are less exposed. You don't have time to question those bits because you're reading the whole time.
Hastings is class. Fantastically over the top and passionate. And the cameo's throughout the show have been top class. Carmichael coming in and instantly cancelling the observation (for budget reasons) could turn out to be a bit lazy from the story writers if she is a bad egg. Everyone is immediately suspicious of her. And Tolmie has blown my mind with that anagram!
