If you like historical dramas, this one won't disappoint you. It's well paced, the writing is solid and the story doesn't let you down for 30 episodes. There is a heartwarming romance, rousing action and heroes that you can really route for. It's about family ties and loyalty, camaraderie and standing up to fight for what's right - no matter the cost and no matter how bleak your chances.
Yoon Gyun Sang is really good as the Gil Dong. He is believable as the Mighty Child with superhuman strength that evolves into a rebel, but is equally believable when his character is beaten down and vulnerable. Kim Sang Joong is commanding as Amogae - Gil Dong's father- who lived most his life as a slave but realizes his strength and spirit. Watching him at times gave me goosebumps. I particularly loved the father-son relationship between him and both the adult Gil Dong and the young Gil Dong.
