The acting of all the main cast was amazing especially Do Kyungsoo. I watched this movie because I love musical and dancing movies. I didn't realize that I would get that and a very deep story about the reality of war. While the story was slightly cliche, it was cliche in a good way. First of all, major props to Do Kyungsoo and the rest of the cast. I think most of the cast had no prior experience tap dancing, so you can definitely see their dedication to acting through work they must have put in to learn how to tap dance so well. All of the tap dancing scenes were so fun to watch. I also enjoyed how the movie got deeper and commented on the reality of war . Overall an amazing movie that I would definitely rewatch after giving myself some time to recover.
