This drama gets a 10 for style, technique, acting and execution among all the other things that went excellently in it. However, I rated it low because it was just not my thing. I watched it, but I thought it dragged in some sections, especially after ep10. The co-orporate espionage thing was underexplained at times, and over done at others. I didn't care for it. Then the leads... all of them were pretty harsh towards each other - except our poor spineless, apologising victim of a female lead. First she was betrayed (after making a stupid decision to take the fall), then she was tormented by the lead. I understand how she developed that woe-is-me, I'm-to-blame-for-all-the-problems-in-the-world mindset, but it became annoying. It still wasn't brain friendly to watch. I wanted her to bitchslap and/or publicly shame some of the people who wronged her at least. The torture and the stalking... no words. I was looking for a possessive male lead to watch though, and this fit the bill in an unfortunate fashion. I didn't like MH's decisions, especially regarding the 2nd female lead. The four leads behaved bizarrely towards each other. I found myself thinking over and over "So you all hate each other? Why the hell are you trying to hold on to each other." I'm not even going to get into character analysis. When I reached ep 13 or 14, I found myself thinking... "Why am I wasting my life watching this?" That's a bad thought for a drama. However, Ji Sung is a draw so I completed it. Upon review of the show however, I found I didn't like the story or characters at all. The poor rating is personal preference. I like romantic romantic dramas with leads who show they care and who can't be torn apart by any 2nd leads. Secret was a bit too dark for me. Ji Sung was wonderful to watch though. His possessive, protective, chaebol character was just right... if it was toned down and in another setting lol. I want to see MH's character totally devote himself to another lead in another show (without the torture). But the story is what it is so I must say objectively that Secret was well executed, excellently acted by all the actors, and the story was a genius of a thing for people who like that kind of story. Objectively, I'd give it a 10. Personally, I'd not rate it so high. Confusing. Music: On spot. One of the best OSTs and the music fit the scenes they were played in. Rewatch: No, because it's not my kind of story.
