After seeing "Woosang" ("Idol"), something happened which I never saw before...and I have seen a lot of movies. Following the movie, many people from the film festival who saw it stood outside the theater---talking about the film and why they felt it was such a confusing mess! Even with bad films at most movie festivals you'll find many who love the picture....but with this one, it seemed that the movie was just too confusing and much of it rather awful. Later, I checked with some Korean reviews...and found that they, too, found the movie confusing!! The bottom line is that there way too many plot holes and the film looked like it was partially edited....but sure not completely.
Overall, an interesting idea for a story marred by bad writing and excessive violence intended more to disgust than to tell a coherent story.
