Not bad at all
For a movie with a 9 million budget this was not bad at all. You have your typical trademark Korean melodrama, which is fine by me, plus realistic looking mayhem scenes, not to mention tons of action, drama and suspense. It was much better than I expected. Never saw "The Towering Inferno" but I can tell this movie does it very good justice.
The towers collapsing was a little too reminiscent of 9/11 and as New Yorker, brought chills down my spine and even after almost 13 years it feels "too soon" to see something so similar on a film, even if it's a foreign one, but other than that this movie was awesome.
