Steel Rain 2 should be separated from the viewer's mind from the first, artistic and touching Steel Rain. Steel Rain 2 is an entity all it's own, a completely different genre.
The plot is non-existent. Not that they didn't write a plot, and that events don't take place, but that the plot is so packed-full with events that don't lead into the next- and complicated, but unfortunately useless action, that I can barely call it a story line. I would much rather call this an amalgamation of short action sequences. However, that can easily be fun for a viewer, so it depends on your taste. I would compare the scope of this film to a Hollywood Michael Bay film.

The cast and chemistry was just as great as you might expect, with the sad exception of Angus Macfadyen. It's wonderful to see western characters have roles in the Korean film industry, but unfortunately the chemistry didn't match with the other two leading actors - who have a great sense of how to perform the play-by-play, back and forth dialogue. This might be a problem with cultural and language differences, or a direction issue, but it was a frequent killer of the excellent chemistry between Jung Woo Sung and Yoo Yeon-Seok as awkward political leaders.

As a lover of OST, Soundtracks and film music, I regret to say that the music was misleading and unremarkable.
