Over the course of three seasons the writer came up with this beautifully written makjang (one of the best I´ve seen in a while).
It was full of plot twists which sometimes we didn t see them coming, making the drama even more enthusiastic, and even when the twists were a little (tag fantasy) the writer made sure to explain everything in detail which made them more realistic.
In the first 2 seasons i gave full 10 stars, and even in this final season with many incongruities, the drama stayed true to its nature, giving briliant twists till the end. However this season was not the best, because even if ALL Hera kids had their own character development and had a fairly happy ending, most adult characters, the good ones had a soulless, heartless ending or the bad guys ending that wasn´t bad enough for their evil deeds.
I must point out Shim su ryeon, who was my favorite character throughout the whole seasons because of her strong attitude, resillience and kindness, didnt match these traits in the finale of penthouse, however I can still understand her ending and others too. It was bad because it was a beautiful makjang but in the end turned out just a simple drama with a basic ending, it doesn´t make any sense, still sad with the ending. Nevertheless I still recommend it to everyone to watch all seasons, cuz only then will you witness the greatness of this series, it is still one of the most brilliant makjangs with greatly developed characters despite the (in my opinion) not so fitting end.
Hope it helped!
