A real ACTION movie ! Seriously If you're into those hollywood-like action tricks like : breaking the walls and being overshoot through the windows , amazing car accidents , shooting 100 people at the same time and then stepping on a flood of blood etc. I highly recommend it ! But ... If you're here cause you prefer asian-style movies with asian-style stories , please listen to my opinion ! Personally , I think this movie tried very hard to be a HOLLYWOOD-LIKE action movie and sometimes used English language for speaking where it wasn't actually needed !!! (e.g : why would two koreans speak English in Korea ?! ) Anyways , you're not watching a romance ! so don't wait so long for a love relationship between a killer and his next traget ... One of the things that made me disapointed about this move was first female lead ! I'm not against her acting (I'm not a fan either) BUT she really couldn't express her feelings as a mother who has lost her one and only daughter recently (or at least I couldn't feel her emotions) ! Through the movie , I kept looking at the time asking myself (how much does it take to be finished ?! should I play-forward ?! ) And I think the real reason for this feeling to the movie was the emotionless actings (specially those foregin actors who were aweful !) and the very slow progress of the story. I really wish they could direct it way much better and wouldn't let the movie to be filled of too many action scenes to get really intolerable ! Anyways , if you're a fan of action movies , watch it over times ! but If you care about the storyline like I do ... Just watch it once - twice to get the whole idea !
