Propose Daisakusen was like banging my head against a wall over and over again.

I'm sure the title rings a bell. We've all seen it... dramas that started off okay (or even GREAT) and then at some point everything went to hell. It's like the writers mixed some crack on their morning coffee and the drama's story starts getting these insane plot twists that make your head spin... and everything that was originally good about the drama is ruined. Even the characters themselves, which were so great at first, suddenly go crazy. The nice guy becomes a murderer and rapist (complete with crazy bloodshot eyes and Evil background music), the great intelligent heroine becomes a screaming and weeping mess, there might even be some Dramatic Terminal Disease for someone. So which were the biggest train wreck dramas you've ever seen? And do you remember what point/episode the Crazy took over? For me one classic example of this was the taiwanese drama "Knock Knock Loving You".

even though it's one of my favorite dramas i have to admit MSOAN just took a sharp left right onto the train tracks about half way through.

For me, it's May Queen. After episode 8,when the time's change for adult phase,that's the point where this drama started to become awful for me.The child phase is really good though! :S

Big. started quite good but then at some point something missing and became boring to watch. Romance Town. repetitive plot and boring as hell. seems like the story actually didn't has a story to tell. Flower Boy Next Door. It is sad that this drama has to be in the list. i only managed to watch until episode 13 and can't found any reason to finish it.

Big fan of Missing You here. I'm disappointed to see it mentioned several times. First off, it is a melodrama, so you have to take it as one. I don't think they appeal to everyone so I can understand why people might not enjoy it. The entire concept of a melodrama is over-emotion, the intention is to assault the viewer with numerous tragedies until it breaks you down, strips you bare and leave only certain feelings intact. Obviously this type of drama isn't for everyone, but it is very well done if you take it as it was intended to be. It's not lighthearted, there are probably more crying scenes in this drama than a handful of other "emotional dramas" combined, but the acting is superb and the themes are universal and heavy. I'll reiterate - melodramas are meant to be sensationalized and will always feature a seemingly endless cycle of tragedy and scenes that are meant to make you feel vulnerable. Obviously I respect everyone's individual opinion, but I wanted to make a case for Missing You. I genuinely feel like it was a masterpiece.
