As long as you put your brain on the shelf while watching, you will enjoy it a lot. The portrayal of DID makes no sense, the villain´s skills are so good, they seem magical as they have no grounds in reality, the plot has a number of plot holes, but oh boy, it was an entertaining ride.

Bad and Crazy presents a rather basic story with predictable plots and twists. What saves it are the characters, comedy and the action. The dynamics between Soo Yeol and K are pure entertainment, delivering the laughs and emotional depth I appreciated a lot. Kim Hi Eo Ra and Won Hyun Joon also delivered a solid performance as Russian-Korean drug gang leaders, making me, and other viewers care for them, and wish them at least a bittersweet ending, even taking into consideration their evil deeds.

Sadly, the plot just does not connect. First and second half feel like completely different shows, shifting from an action comedy to a mystery thriller. Plots and characters were gone for a good few episodes, just to bring them back later on, as if it does not create pacing and continuation issues.

The last two episodes serve as a rather mediocre conclusion to the plot. Everything happened too fast with not enough explanation. They dropped all the information on me and I was supposed to just accept it without asking any questions. The moment you start asking , you see how the whole plot crumbles.
About the bad guys - the corrupted, the business duo, the magician. Out of them all, only the Russian drug dealers that were focused on their business and making money were realistic, interesting and made me curious to know more about their past, goals, reasons and motivations. The rest was either predictable and full of cliche or borderline supernatural making it unrealistic.

Performance wise, Wi Ha Joon stole the show. K was the heart, soul and the driving force behind the drama. I laughed, I cried, I fell in love - all thanks to his portrayal. That said, the whole cast did a stellar job with their acting and delivery. I truly could not think of one example of even mediocre acting. With such a cast, it’s not surprising.

The soundtrack just paved the way and got me excited at all the right moments. Not surprisingly, tvN delivered in terms of production value. I especially loved the long corridor shots that represented Ryu Soo Yeol’s consciousness.

Overall, the comedy, K and Boss Yong were the elements I truly loved and appreciated the most. Would recommend it as a fun and entertaining watch. Even if you won’t get absorbed into the plot, you will most likely appreciate the comedy and the action.
