What was the most stupid drama you watched?

Princess Princess D. Stupid premise and overacting are usually my jam, but Princess Princess D was so badly produced that even I couldn't feel any enjoyment in watching it ironically.
Lol, real_ Mokona, I wouldn't call any of the dramas I watched to be of particular didactic value (meaning that they would teach me a lot), but I can't say that any of them was just stupid stupid. It's hard to say. Those shows are made mostly for entertainment, so they are good for what they are... That being said, I did have some trouble understanding Mischievous Kiss. I kept watching it and wondering why on Earth those people did what they were doing.
Fall in Love With Me. The first half of the drama was pretty decent, but after that it just went downhill, especially due to the second lead. I have never seen a character to act more stupidly than her and her reasoning behind her actions didn't make sense at all!
