Okay, it's a close duplication. The third season on in the original didn't cut it. But the cultural differences made the Korean version better. The action was tenser and more consolidated. I liked the characters better. They seemed far more real life and engaging. But the defining element for me was was the musical scoring and direction. You were actually compelled to follow the actions of the actors. The Korean version acting President was a real person in an impossible situation. The US version was also good, but it was and actor- albeit a good one - portraying a role. Some people have given reasons for liking either. You can't go wrong with either. The score and direction of the music was absolutely brilliant. The show wasn't bad either.
