This drama was destined to fail from the beginning. Some of original selected main cast dropped off. Some cast controversies prior to filming. It was cut down from 50 episodes to 26 with premature ending. Conflict between cast. Lee Tae Im absence in the last 5 episodes because she got into an accident, they were even planning to replace her but the drama ended anyway. The writing department suffered immensely, the drama was full of delirious characters. Some complain how stupid Soon Jung is but the real smooth brain is actually Soon Jin, I believe apes have higher intellectual abilities. No wonder why the broadcast ratings were abysmal. Thankfully, it ended early anyway.
