I love Shetland but, while still great drama, this was my least favorite season of all. The character of Olivia may be one of the most unlikeable non-criminals in the entire series. She is constantly making bad decisions, never gives a hint of gratitude, and really made me dislike the series (just a little). Loved the Tosh romance storyline. Jimmy being forced to question or not trust a person close to him (Alice) is repetitive from last season when he had to question Duncan's involvement in possible criminal activity. I hope this series isn't the start of a downward spiral for the show as I am a HUGE fan. As always, brilliantly acted and scenery is amazing.
