Very enjoyable thriller

Rating: 9/10 (14 September 2005)

Very nicely done with neat twists and turns in the plot ! Visual effects were pretty well done.
Very well acted and paced.
One gripe was the main character gets a bit overly melodramatic at times throughout the movie, but I think this is a form of Korean machismo, and I've definitely seen this type of Korean machismo firsthand. So I guess it's true to life.
This movie reminds me of the mathematical object -- the Mobius strip. Watch the movie and I think you'll understand what I mean.
I think one fight scene should have been reworked by the director to make it more believable (the one involving the hammer).
The last scene -- I didn't see it coming, but it fit the movie perfectly.
