I will try my best to mention everything without any spoilers, so I apologize that this is a tad bit long, but an excellent drama deserves a long review!

To start: I love this drama. How the story unfolds perfectly with each episode, to how the characters carry the story with their actions, this drama is perfect. For me, enjoyment is the main factor to determine if I like a drama or not. If there are a few inconsistencies but I ended up enjoying watching despite them, I will still like a drama. For Penthouse, there were a few things here and there that I think could have been done differently, but I didn't dislike the drama less because of it like I usually would for others. There were barely any inconsistencies that ended up enjoying every moment I watched enjoyable.

Story:
As long as a makjang drama is done right and makes sense, I don't mind how dramatic it comes off as. For Penthouse, it had the right blend of insanity with the plot and characters which made it work well (for me). What I love about this drama is how it's not predictable. Sometimes it comes off like you know what's going to happen, but then it throws you off-board by going down a path least respected. The overall flow of the drama was something I also really liked, as it never felt slow but at the same time it didn't feel like things were happening so fast. It had the perfect pacing, which helped keep me on board and made me enjoy the drama more. Another thing I really liked was how each prominent character gets focused on for a few sets of episodes instead of the story of each character getting told in the same episode. Because of this, each episode doesn't feel jam-packed and is able to properly tell the character's story without rushing anything. Overall, the plot was extremely enjoyable and constantly fascinated me which made me enjoy it more than I thought I would

Characters:
One of the bests things about this drama is no doubt its characters. Not just the three leading ladies (Soo Ryeon, Seo Jin, and Yoon Hee), but the leading men and the supporting characters are what make this drama spectacular. The acting is well done that sometimes I forget to separate the characters from the actors since the portrayal of each character felt so real. I also applaud the younger casts for how well they did with the intense script they were given. Penthouse gives you characters to like, characters to hate, and characters where you can choose whether you want to support or not. This balance makes the character ensemble interesting and enjoyable to watch, as you never know what will happen or what each will do.

Others:
Despite only getting to 3 OST's, both of them, especially Crown, was really good and fit the drama well. I also like the usage of classical music, which fits the overall drama extremely well. I also really like the design of Hera Palace, and even forgot a few times that It was completely made of for this drama.

One thing for sure is that this drama is not for everyone. If you're one that gets easily enraged or is sensitive then this drama might not be for you because of how intense and "dramatic" it is. However, I don't think because of that this drama should be labeled as "bad," since that is a preference.

Final Thoughts:
Penthouse will go down as not only one of the most intense dramas I've ever watched but also as one of my favorites of all time. The intense, unpredictable but fascinating plot captivated me and made me excited each week for new episodes. Penthouse was a drama that I didn't anticipate as much as others, but I ended up loving it more than the ones I anticipated.

I can't wait to see what happens next in season 2!
