I hated Oh Ha Ni, but I did struggle thru and finish PK...
One drama that I dropped, and I know people are gonna wonder why, and I will prolly get stoned.. but eh.. I dropped Freeter (something or other, the one with the guy from Arashi).. I tried like 5 times to watch this drama and each time I couldn't make it past the first 15 min of it, I was falling asleep each time..
Another that I dropped was Love Buffet: If I thought I hated Oh Ha Ni, its nothing compared to the loathing I felt for the lead girl in this drama... I thought "Ok, I can make it thru this, I can," but no.. I got so sick and tired of her indecisiveness, crying, and only one REALLY hot guy to look at, just wasn't enough to get me to finish it..
