Korean dramas are known for their stereotypes. The overarching story may change, the genders might be revered (figuratively but in some cases literally), the girl might be rich instead of the guy, the witch may get the man instead of the princess, but the major beats are always the same; guy and girl are meant to be, blah blah gets in their way, they get together in the end.
True that some of the recent entries have tried to shatter major stereotypes (take Weightlifting Fairy Kim Bok Joo for example) but no kdrama breaks stereotypes the way Be Melodramatic does. Most kdramas start off funny and light hearted, then quickly shift to the same gear that every other kdrama does with over the top melodrama and sadness, oh so much sadness.
Be Melodramatic has surprisingly managed to balance the tears-in-your-eyes comedy, heart throbbing romance and poignant melodrama that never goes over the top in such an effective manner that I doubt any other kdrama comes even close. The fact that this is such an outlier in the cookie cutter world of kdrama might be the reason behind it's low ratings. In being so different, it may have alienated some of the typical audience members for this type of media. But if people aren't hyping this kdrama up to the max, they are making a mistake. This drama is awesome.
To those who are skeptical of this show, just watch episode 1 till the end. You won't regret it.
