Good concept, nice first episode and a decent selection of cast. However, for a thriller/mystery drama, the writing was unbelievably moronic to the nth degree. Blatantly mocking the viewers every step of the way. Every minute decision was deliberately stirred away from any sense of reason for the least optimal result possible. It even failed to deliver something with its climax, the whole last few episodes were the weakest in general. The drama ended up being disappointing therefore it is hard to recommend it unless you are a fan of some of the cast members which they did a decent job at least.
