I'm giving this drama a 10 because this is the most emotionally involved I've ever been in a show. I'm not claiming the show is perfect but I feel that it offers an engaging, amazing experience. I wasn't even going to watch this because I was worried the drama would portray autism either as a party trick or something that made someone useless, but Park Si On was an amazing, complex character made more so by superb acting. The secondary characters are not always likable but in this drama everyone is given a chance to redeem themselves and most do. I'll admit, there were a few flaws. The rewatch value for me in a 7, because I'll be skipping certain scenes. (I'm not upset I watched them the first time, though.) The politics started out taking up too much of the show, and in the beginning few people were on Si On's side. The abuse he suffered was painful to watch- but I think that was important. People with disabilities are often treated badly, especially when someone hasn't met them before. Pretending this doesn't happen might have made the show more comfortable to watch in the beginning but not as emotionally affecting. When people start supporting Si On, you really cheer. And there were always comedic moments, and of course the amazing In Hye. Favorite character ever! Really, In Hye alone would have made me give this show high marks.
