The story line is really well done. The bromance between the guys is phenomenal. It is definitely a teen KD. However, I am far from being a teenager and I still enjoyed it. The ending was well done because it left it to interpretation. The characters really grow in this KD while staying true to their original selves. There is of course angst, but it is not so over played that it feels contrived. Sometimes when there is angst in a KD, the characters act…well, out of character. Not in this one. The music is good and I found myself humming them after watching an episode. The background is gritty and seems like a natural setting for the characters. My only complaint is that I didn’t get to see more of L, which is why I started watching Shut Up in the first place. However, I did enjoy the rest of the actors and of course they are cuties. That drummer (Lee Hyun Jae) is a hottie with a great smile!!! Over all I would say this a KD that you don’t want to miss!!!
