Memorable Fight Scenes

It shows how much Ji Chang Wook trained for these scenes and they were filmed in a cool, 3Dish type way.

A few of them, but the one that stands out for me is the first time she meets Shin Se Gi.

Jang Na Ra's fight scene in her apartment was fantastic.

The guy that gets stuck fighting the leader of the gang over and over...those were some great scenes.

That historical battle scene in episode one was gorgeous.

More memorable for how it was filmed than technique. In the beginning of the second episode the fight scene had a contrast of slow motion and then sped up when the punches landed. Visually interesting and made the hits look like they landed harder. 

That show was such a fun ride with so many great fight scenes even starting off in episode one with the warehouse. They were such bad asses you did NOT want to mess with any of them. Loved the plunger, lol.
