Ah really? Most of the ones that I have been watching over the past year have been 24 episodes long. I guess it depends what it is and how the reception to it has been throughout filming, since some are still in-progress even as they start to air. Guess it depends on the storyline too, there is only so far you can spin out a standard plot, whereas ones with more twists and things will take long to resolve and need more episodes.
I keep meaning to watch 1 litre of tears, but I have other things to watch before that XD I have 2 episodes left of 홍길동 (it's taken me SO LONG to watch it because I love it so much that I just don't want it to end!), and then I'm planning on watching Beethoven Virus, and Boys Over Flowers. I try to not have more than a couple of dramas on the go at the same time, or else I get mixed up with what's happening where XD; I also wanted to finish Fantasy Couple and My Girl, but I've forgotten where I'm up to on both of those e_e
I tried to watch Winter Sonata though, and couldn't get through it. It was getting so depressing!
I liked the tricks and stuff on Liar Game too, the concept itself I liked, it was just the acting XD but that is my problem with a lot of jdramas, and if the story itself is good enough to keep my interest then I can sit through it and ignore the acting. Like Ryuusei no Kizuna, I finished that one a couple of weeks ago. I absolutely adored the story though, and was hooked on it. Same went for Code Blue, the acting may have been questionable quite often (compared to Western medical dramas) but I loved it anyway (... I loved Yamapi's hair in that most of all). Really though, compared to some other jdramas, those things don't seem like over acting at all. It's just a bit of a mixed bag, and comes down to personal taste, I have friends who are totally in love with this drama or that drama, and for me to sit through even the first episode has made me feel like someone dragging their nails down a chalkboard. And then vice versa, there's been some stuff that I've adored and my friends have hated it so much. HAHA my friends and I are a mixed bunch, we either have exactly the same taste, or exactly the opposite, and we never know which it's gonna be XD
