For Crash Landing fans this movie is quite a fun watch because Hyun Bin acts as a N Korean soldier plus he looks cool as the action hero here. The odd couple buddy cop thing works well with some funny moments along the way. The action is convincing. The one fault is it is a bit long especially the last part seems unnecessarily extended.

This is an interesting action thriller, but felt unnecessary detail got in the way of a film that could and should have been significantly faster paced, and could have cut the running time. Honestly, there were scenes that made me wonder why they were added to the final cut. Towards the end it does gain pacing and it is an exciting thrill ride.

Hyun Bin was excellent as Detective Lim Cheol - sleek, classy and tough. I really enjoyed him in the lead. Hae-jin Yoo was a bit too tongue-in-cheek-ish, although his performance was very good during the climatic final battle. The two actors did complement each other, though, and the trust issue between the two was effectively done, being North and South Koreans. In general, this was a good film.

North-South Korea relation is a popular subject in Korean cinema, every time movie like this come out, it will be surely become box office and get wide local media attention. I like Yoo Hae-Jin, he is the Korean greatest supporting actor of all time other than Oh Dal-Su, you can see his face in every big time Korean movie. Lately he got a lot of main character role, good for his career by the way.

About this movie, you've seen this a lot in Korean cinema in every movie about North Korean spy and everything. But, it still nailed you in your seat. It got a lot of comedy moment that make me laughing out loud, Yoona from the Girl Generation surely give her best as a comedy relief role. Too bad her screen time is not much. If you love suspense, Asian action comedy that to be honest is way better that U.S nowadays. You can enjoy this. Have fun!
