No pun intended - Korean movies. You have to love them. Of course not all will have the same amount of quality, but if they get a cinematic release in Europe (around the world), you can guess that they are more likely than not a winner .. a good one of sorts. And I can clearly say that the movie is well done (like the puns I use - another one in the previous sentence).
That all being said, this is based on a true story. Not sure how much of it actually happened the way it is being shown - but a little creative license goes a long way. The actors are really good - so good that you may not mind when the movie is a bit convenient and coincidences happen that seem way too far stretched (again do not know the real story, so maybe some of the stuff happened like that anyway).
Still the movie has high drama and the suspense works really good. You are on the edge of your seat - car chases, shootouts and twists and turns! Some you may be able to guess ... others not so much. I really loved it ... and I didn't mind the melodrama or clcihes it did dish out ... they make sense in the overall arc and theme of the movie.
