Remember

The first 4 episodes were dedicated entirely for their backstory and they did an outstanding poor job in that regard. These first 4 episodes were painful to sit through, unbelievably boring, lacking any interesting or gripping elements and it failed to lay the groundwork for things to look forward to in the future episodes. If that wasn't enough, the main story was mostly shelved and the subsequent episodes turned into side cases with slight relation to the bad guy until it returned to the main case in the last few episodes. Although the male lead was labeled as a genius and has super powers but his character proved to be otherwise. Namkoong Min playing a pathetic low-life chaebol playboy villain was definitely a miscast. It would more suitable for him to play a smart cunning merciless villain but the director was blind. On the other hand, Jeon Kwang Ryul playing the main victim with Alzheimer and being a good loving father was weird, another miscast and oversight from the production. The trend continues Park Min Young playing a prosecutor, it's just not it.
