This show is one of the best crime dramas I have ever watched and I've watched quite a few including Law & Order SVU, Broadchurch, True Detective, Mindhunter and Criminal Minds.
The first season is kind of meh and makes it difficult to convince people to watch the show. But from there, it gets so much better. The setting is beautiful - I am now determined to visit Shetland. The acting is amazing without being over the top. The storylines unfold so slowly but in a way that doesn't feel rushed or so farfetched as to not be believable. The characters are all so rich and multidimensional and. each one develops in their own way over the seasons. Best of all, the writers have made it almost impossible to guess the "whodunnit" of the episode...I have tried and failed on numerous occasions to beat DI Perez to the punch. 7 seasons of this show is simply not enough and I so look forward to an 8th season.
