Calling this drama underwhelming is an understatement. I can't express how disappointed I am with this drama..A rich female lead, a money hungry cheating husband, a psychotic mistress, a loyal brother.. Well it definitely had all the right characters and basic plot to make it a perfect drama.. But sadly it lacks a good writer. The plot had so much potential but was executed terribly. It feels like the narrative is being told to maximise tension for the viewer, rather than playing out in a naturalistic way. The more one sees the main characters, the less appealing they become. Female lead is so weak that it will infuriate you. The fact that she is a heiress and can do nothing but watch as her penniless cheating husband keeps a mistress and is trying to take over her company is so crazy. Her husband is gullible and not even that smart (except on few occasions) and this makes the fl's character even more weak. The mistress on the other hand is the most powerful character in the entire drama. She is strong, revengeful and does anything and everything to get what she wants. Now coming to the fl's brother, he is fiercely loyal to his sister but somehow his character is kind of dull and not used to it's full potential. He tries but never truly rises to the occasion. Well atleast his character does better than the fl. Throughout the drama you will keep thinking the revenge and mindgames will start now but nothing really happens which will frustrate you further. By the end of the drama it’s hard to not think that the plot resolution is a bit, well…silly and convenient. The mistress is both the villainess and the heroine towards the end. It's like she is the only one who is taking action throughout. If there are any penthouse fans I suggest you stay away from this drama(esp if you are expecting the wife to rise to the occasion and become smart like shim soo ryun).
Now coming to the acting part, I think all the actors did well which was the main reason I could keep going on. In fact I think this must be Jeon somi's career best performance.. Her acting was brilliant. OST of the drama was good.. Watch this drama limiting your expectations then you might enjoy it.
