The fact that Soul is so ignored and overlook is considered a transgression by me! The fact that it's buried deep, deep under so many (over)hyped dramas regardless their genre is distasteful! Soul is a deep, dark, thought-provoking drama; not for the timid and demure people (i guess, that's why it's buried).

Story
The drama is an excellent and unique combination of horror, crime and psychology that actually works!

First few episodes, and the drama is rather weird, difficult to follow at times, too many seemingly unconnected stories, dark and gritty cinematography. What the actual hell? Horror. If this drama does one thing right is setting the atmosphere, noone can deny that. The female lead is a likeable girl who can see ghosts and ultimately be possessed by them. The drama is possibly the only kdrama about the supernatural and ghosts which actually tries to be... not scary, but rather creepy and spooky, and it succeeds!

The girl wants to avoid them, be free of them and be normal, but she can't. And there is one guy who makes her feel safe and can potentially help her. No, not in a cute/romancy way, no, the script is just too good to resolve to romance to be likeable! The guy is a genius psychologist and crime profiler with a dark past. He does help her, or... that's what he wants us to believe! Plot twist? He uses her in reality to get revenge for his dark and sad past! And here we have the base concept of the drama which isn't really obvious from the beginning. Revenge, and its repercussions.

The drama pretty quickly switches from horror, and moves on to crime and psychology and here things get serious and interesting fast. Soul wants to address several morality issues and negotiate the very core of the human identity. It revolves around the idea of serial killers, how are they made, what do they think, can they be saved? What does it mean that we can examine and judge our own emotion-driven behavior and that of others? Can killers still be considered human? Where are the boundaries of responsibility between stepping up and overstepping? Can violence be stopped without more violence? Can there be serial killers who are not psychopaths? And in the very end, when we do step up are we better than those we hunt? Is there a difference or it's just an endless cycle?

The drama is very twisted in the best way possible. It is thrilling and offers several plot twists. It did have its boring moments and some problems of discontinuation while it took a few episodes for the plot to connect all the dots and find its way. Nevertheless, it was a fantastic overall experience. The story was to the point and quite fast paced. I can't say it was unpredictable but that didn't stop it from being interesting.

Acting
Lee Seo Jin shines the most in what i want to describe as one of the most twisted and yet most sentimental characters i've seen in kdramaland. He delived on several levels being sensuous and pleasing to every sense.

Im Ju Eum's role was rather demanding. Her character walked in the fine line between vulnerability and helplessness. I thoroughly enjoyed her 'crazy eyes', she suited the character completely and i think she really felt it. There were scenes where she was really incredible, and other were i felt she overacted quite a lot. Overall, she was great, and quite memorable, if she hadn't been lee seo jin's character wouldn't have developed and worked as exceptionally as it did.

I want to especially mention Lee Kyu Han for his amazing performance as a disturbed serial killer and Yoo Yeon Suk for his impression of a serial killer in-the-making.

Recommend/Rewatch
This drama isn't child's play, it's rather heavy and difficult to digest. I wouldn't recommend it to everyone. If you are a crime and psychology fan, this would appeal to you. Horror is present but takes the back sit rather quickly. I can see myself rewatching it in a few years.
