I'm not getting bored with it, I love it and like the fact that a lot of the characters are developed and have their own story. I love Archi Panjabi as Aisha, I always thought her character more interesting in 'The Good Wife' than the main figures (gone off that series in the last year, the main characters are so smug ).
I've decided to start reading the Shetland books, having been told that the tv series is a good representation of them - I've read most of the 'Vera' books which are by the same author (Ann Cleves), and she too is portrayed well in the tv series, (also on tv at the moment)by Brenda Blethyn, but I find I fall asleep during them sometimes as they can be slow and are on for two hours, as each episode is a complete story.
