This show had everything to be top-rated but fell flat for me in attachment. The drama had a very interesting plot line which reminded of SAO Ordinal Scale. It was shot beautifully with a grayish scale tone being always present. Hyun Bin and Park Shin Hye did a fantastic job in their roles with Hyun Bin obviously being the star of the show as the one man army against all odds. The romance was present, but it wasn't one that made me excited or happy, even though there was good chemistry. I was relieved the Park Shin Hye was finally able to kiss properly against her last drama. The show portrayed how even just one person's faith can mean the world to you and be a pillar of strength to keep moving on. There were plot holes as you neared the end, and the ending itself was very bittersweet and open-ended. The OST was seriously outstanding though like it came out of a freakin Skyrim game.
