As someone who has seen 2 seasons of the original Suits I cannot say that this remake was better or superior than it's predecessor. However, I thoroughly enjoyed the acting from both PHS and JDG as well as the storyline, so I can't knock this series entirely. Although you may find some aspects of Suits boring, it picks itself up and really powers itself to the end with vigor.
One of the most endearing aspects of the show is watching Yeonwoo and Kang Seok's relationship develop into a fruitful bromance and I can say this is what binds the show together and makes it that much more compelling to watch. The biggest factor that made me want to continue watching was how it took the cases from the original and molded it so that it fit Korean culture as well as bringing an unique spin to every situation, allowing viewers of the American Suits to feel that they weren't just watching a scene-by-scene copy of the original. Every episode has a take home message and displays the morals of every person in the show, as a lesson to viewers and I really appreciate the dedication to detail with the quotes and the consistency of the story writing. Perhaps a Season 2 is unlikely in K-drama world but I definitely would not be against the prospects of one if it is as fun as Season 1.
