As an American and a huge fan of Hollywood action films, it would take a lot for me to rate this a ten. Armageddon(1998) and Apollo 13 (1995), this is not. However, the potential is there but doesn't become realized until the 2nd third of the movie. It becomes more intense. You begin to care about the characters. The final 3rd hammers it home and you're not so concerned about its start anymore. The action, the acting, and the suspense are great. You're on the edge of your seat. You cry. You cheer. Once you finish the movie, however, you become upset about the weak use of dynamic Korean actors like Kim Rae-won, Lee Yi-kyung, and Lee Sung-min. Then you wonder why the beginning was just so so. Budget issues? Perhaps. Even though Do Kyungsoo is the star, making others have a stronger presence would not take away from the star. No one took from Bruce Willis' spotlight, but the entire cast of characters in Armageddon shone brightly because it was so well-written. Finally, the music score needed a little work. Ijs.
