THIS DRAMA IS DEFINITELY A MUST WATCH! The first episodes of this show were addicting, and got me hooked immediately. The plot is amazing and very well executed & distributed throughout the whole show. There was never one time where I felt that the plot was dragging. The ends of the episodes always ended at a note that left the viewer wanting to know what happened asap! All the actors in this are talented, and portrayed their roles well. I was a bit reluctant to watch this because of how Yuri was casted, but she proved to be a better actress than I expected. Uhm Ki Joon and Ji Sung were definitely the MVPs of the drama. Amazing acting from the both of them. Ji Sung's emotions were so raw and realistic, while Uhm Ki Joon perfectly played out his psychopath role. The OST is so good...not the best in my opinion for a drama, but it always added to the scenes, and intensified the moments when played. This is one of the only dramas I watched airing that I have not dropped...Each episode is worth the watch. Despite the darkness of this show, there are many hilarious scenes within...the bromance between several of the prison mates is truly heartwarming.. Overall awesome drama, love all the characters (even the antagonists) ..if you love shows full of action and thriller elements, yet also have comedy sprinkled in the middle, watch Defendant.
