Rooftop Prince is a classic K Drama that one should watch, although, the further you are in your K drama experiance, the least good you'll find this one. First of all, the idea was interesting and entertaining, with the romance good enough to keep things interesting till the end. The past story was okay too and the family drama was good as well, with enough drama to keep you going. But, the drama was full of cliches, with the missing daughter, the evil male rival, the rich grandmother etc etc. At least the theme was original. In addition, the length was too much, as it could have been a few episodes sort. And yet, the ending was a bit too quick, leaving things hanging. So, 5 out of 10.
