In terms of the scale of this movie, the extras, the production values (very high!), the excellent plot, the quality acting, cinematography, you name it, this movie has it all. This is the kind of larger than life movie Steven Spielberg might have made, if he was Korean, quite extraordinary. I would say though that the CGI, while very good, isn't "quite" as good as the best that Hollywood can do, but it's still extremely well done. It's not a family movie though, there is some extreme violence in this movie, but war is war and war is very violent. The movie does take some liberties with the story, I'm not sure all of it is 100% historically accurate, a lot of it "is" true though, like the fact the island was mined for it's coal, but a lot is included for the sake of making an interesting story. It does cover some aspects of the Japanese army's behavior which is an enduring national shame for that country, such as the use of "comfort women", i.e. Forcing Korean (and other nationalities) female prisoners to be the sex slaves of the Japanese army. I can honestly say, some of the best movies I have ever seen in the past few years have come from South Korea. The quality of the movies coming out of the South Korean film industry are every bit as good as Hollywood makes, and in many cases better. Terrifically entertaining movie. Well worth your time to watch.
