" Psychopath diary " blended the genres of comedy and thriller so well that the drama was entertaining till the very ending.
First of all, kudos for not adding romance in this one. The relationship of the main character and the leading lady was pretty great, with nice chemistry and amazing dynamics. Their pairing was pretty clever and entertaining.
The performances were fantastic too. Especially the leading actor was phenomenal, and probably one of the reasons to watch this drama.
Also, the cemody elements were plenty and they kept them up till the final episodes, although, I have to admit that they were less and less as the drama progressed. The thriller and action scenes were really good too, especially the mystery-criminal case was very entertaining.
So, overall, eight out of ten.
