Lots of negative reviews and maybe I can see why - it's not easy viewing but the more I watch the more fascinating it becomes. So often with crime dramas one can sort of see where things are heading - that's what makes them reasonably easy to watch and enjoyable and somewhat bland. Rellik turns that on it's head - the impressions and ideas one builds about the characters and plot may be completely undermined later in an episode or in a subsequent episode - a twist that, instead of changing the future story arc, means you have to change your understanding of what you thought you already knew. I think it's incredibly clever writing and plotting - the more one engages with it the more engaging it becomes.
