Duel is great tv show made in Korea. Duel is by far one of the best online tv shows I've ever watched. This tv show got everything what a tv show should have, and I'm assured that anyone who see the full tv show Duel will enjoy it. You just have to watch Duel. I've been a big fan of such cinema for some time. Duel is one of the best possible choice for a saturday evening with cinema.
