I guess I'm a little biased because I love Choi Min Ho and SHINee but putting that aside, it's hard for a drama that was based off of a manga to be bad (when it comes to plot line at least). I love this drama because it's not to fast or too slow and character development is really lovely throughout the series. On top of that I feel that ALL of the actors are good and have a place in the show which I often don't feel in most dramas. Each of the characters are very important to the show and they all have definite purpose. I would definitely recommend this drama to all kpop/ drama fans especially. The music is absolutely fantastic! I would have to say that was my favorite part of the drama!
