The overall story was pretty decent and the psychological evidence in the drama itself is pretty legitimate. However, if you're expecting something along the lines of the webtoon, then the drama is going to be somewhat of a disappointment. The cases are not very similar, but the psychological analysis is. The characters are somewhat more involved in the drama compared to the webtoon, however this isn't a drama to watch if you really want in depth character development. In my non professional opinion, they stopped trying to create a certain image of some characters mid way through the drama, making them seem completely different toward the end. Also it's an OCN drama, which means it's more of a mystery/detective drama rather than more psychological. If you're thinking this is going to be more psychological than detective then you also may be disappointed as well. Watching this at first, the detective cases were a bit of a surprise and take away more of the psychological aspect of the drama. Overall, it was a decent detective drama with an educational (psychological) side to it. (it also helps that the main guy is attractive :D) If you're ever bored and want something interesting to watch, then I would recommend this drama. It's relatively short, so it's not like it's going to take up months of your time.
