I watched it recently and I have to say it's the most overrated drama I've watched: characters are not very smart and the answers to the mysteries are revealed to the audience way ahead, so even if you didn't guess yourself you feel like you are watching two morons most of the time, the final episodes are the worst, I had to skip like half an hour of people crying over some stupid shit. It's not bad overall, but the 9/10 vote I've seen everywhere online is a joke. If you like actual thriller crime dramas I'd say drop it, 'cause it's mainly focused on the lead couple and their dynamic not so much on detective work
