the action is very well done but a few things about this series put a bad taste in my mouth. so much of the police/investigative work feels like it was written by people who never actually researched how these things operate, (unless the standard is different in SK). i can't count how many times i rolled my eyes at or laughed at or wanted to skip through scenes where the plot was thoroughly unconvincing because of this. whenever a series does that, it just pulls me out of the story and makes me focus on more technical aspects. secondly, too much of the plots' progress was due to happenstance. while it did have good writing in there, ultimately, the "conveniently finding an answer to this problem that doesn't really make much sense in the bigger picture" got in the way of my ability to enjoy the series. there's also a lot of weirdly placed english in there and being a native english speaker, it was a bit hard to take seriously. but the final straw was the ending. it felt so detached and the lead up was very choppily sewn together. the only thing that would make me see this as slightly less of a problem is if the series gets a second season, otherwise, it's a very poor ending to an interesting premise. the acting was pretty great, nonetheless. and the music was very moving at parts. but all in all, good, suspenseful action isn't enough for me to give this a higher rating. perhaps these things aren't things that bother you too much, so watch for yourself and judge.
