As with S1, I like the idea of the storyline, but at times, it's just too far fetched.
Also like S1, the killer is revealed slowly, before he's caught, so we know who the main bad guy is, well before the end.
I like Jang Hyuk as an actor, but Lee Jin Wook filled his shoes pretty well, with a character far more quiet and detached, with not a few personal problems.
The serial killer this time, whilst equally formidable, is not as evil or scary as Mo Tae Goo (he was the devil incarnate), but chilling nevertheless.
Again though, it gets very far fetched at times and there are real weak areas in the plot.
There were still some surprises too though and it's as violent as the first.
I did feel that at times some actors were literally just reciting the words, as on occasion their acting became stunted and kind of uncomfortable.
Unlike S1, this one will lead into S3, so I can't really comment on the overall ending, which left us in no doubt of more instalments.
I will watch the next one, but hope that the dialogue and realism will improve.
