Yes there are sex scenes and you know what? They're really well done--sometimes sensual, sometimes raunchy, other times like a work of art. It honestly adds to the experience of the movie. If you're bothered by sex then don't watch? I've watched The Treacherous twice now and I loved it even more the second time. The cinematography is really great and the acting is really well done too. If you're into saeguk dramas, you'll love certain aspects of this like the inclusion of pansori by the narrator as well as some of the character, the traditional sword dancing, and of course the ever present court politics. The King was the most interesting character, mostly because this is based off true history. My understanding and knowledge of Korean history is mainly from what I've watched in dramas (lol) so I'm not sure how much artistic license they took with the portrayal of this tryant king, but MAN was he out of his goddamn mind! It was insane! But that's what makes this movie so wild and enjoyable--there are almost no limits to the insanity...its raunchy and violent at times, but that's supposed to be the point. The film explores greed, power, lust, revenge all very dark and entrancing themes that really draw you in. The camera work really helps to add! Honestly, the rating is probably so low because you have viewers who are used to watched sappy, romcom movies and dramas and this is definitely no where near that sort of story. If you're looking for something gritty, explicit, exciting, sexy, and just insane you will not regret watching!
