This show is without a doubt one of the best series I have ever seen, the plotline sounds so generic however I was pleasantly surprised. The acting is incredible and the music is perfection and I don't use those words lightly. I was so sad when it finished because I doubt I would be able to watch something of that callibar for a long time. I highly recommend watching in Korean with subtitles because anything else just doesn't cut it. I have one teeny tiny issue with this show and it's that people can get stabbed multiple times and still fight, of course I haven't been stabbed before but I've been led to believe that if it's not treated soon after it is fatal however mabye I am wrong but either way I would still give this show a 10/10. South Korea recently have made some fantastic shows, original ideas with great plotlines. American shows recently I have found quite stale and repetitive.
