Now that I finished it all, I believe I have the right to judge it fairly. First off, the main actor Lee Seung-gi was really great. I felt like his acting fit the role perfectly and that he was very good at portraying the character he played. Cha Seung-won also did a good-ish job. His acting was okay-ish maybe it's his role but he did well. When he was in pain or angry he portrayed those actions perfectly. The rest of the cast were good as well but the lead actress was always on my nerves. Oh Yeon-seo was what I struggled to swallow. I honestly don't know if it's her acting or if she was actually supposed to be that way but I felt like she was extremely slow and cold and also standoffish at everything. She did an okay-ish job but I just couldn't stand her that much. I also felt like the relationship between her and the main actor was a bit strained and that he was giving his 100% and she hardly gave 10% but it's all the storyline's fault - at least thats what I'm putting the blame on - but that's my opinion and what I felt like. Not to mention, but the storyline was a bit rough around the edges but to be quite honest I overall enjoyed this series and it will be missed.
