Watched this while on a plane to Seoul. I am a fan of Lee Jun Ho and was excited to see he is playing the main character in this movie. It was difficult to watch, it got pretty boring after 15min. Although I do like the historical aspects and modern K-culture references in this movie, the storyline was not well-executed, having a lot of potential. Personally, I would say the acting was the best, even though it was still mediocre. Not much to say after that. Not very impressed, giving it higher points just for the lead actor. If you are interested in light-hearted historical Korean dramas, you might enjoy this though.
