Well for me that would be 1 Litre of Tears, too. It was so sad.. :(
One Million Stars Falling from the Sky. That drama had a huge impact on me.
Autumn Tale was extremely said to me :( I also cried my eyes out at The Moon that Embraces the Sun...
-I am sorry,I love you -1 Litre of Tears Well I would add "Rooftop Prince" (you may wonder "why" lol).But It's because..I don't want to spoiler :o.Anyway It just ended the way I didn't want to.I mean,It was a little bit sad to me ._.
For me it could be either Sore wa Totsuzen Arashi No You ni or Tatta Hitotsu no Koi. They are not super sad but since I dont like watching teary dramas they are sad enough for me :)
I don't watch a lot of sad movies. Lately, the main reason is because I've been having problems with my cornea. So every time I cry heavily my eye hurts extremely bad (minimal tears are okay). So I try to avoid the real tear-jerkers lately. I need less crying. But the last dramas I remember watching where I really cried were Scent of a Woman and Stars Falling From the Sky. I can't bring myself to watch another tear-jerker any time soon even though they are on my list of "plan to watch".
1 litre of tears. I was bawling my eyes out D:
Stars Falling From The Sky, although it wasn't my favourite drama, it was still saaad ): Movie: Koizora & A Moment to Remember I still have to watch 1 Litre of Tears, but when I watch sad things I get depressed so it'll still be on my PTW for a little while ;]
Does a Movie count too? >_<
*grrrrrrr* The supposed to be funny Movie from yesterday
"The frozen Flowers" was really,really,really,really,really,really sad :(
I cried so much at the end. That stupid queen.That stupide king.That stupide fave-main-lead-of-mine.THAT STUPID,EVIL MAN at the end which name I just forgot.*He killed off my gawussie even though he seemed to survive.He did deserve it but NO he was killed by that.......creature***!
AUTUMN TALE - I cried so much, & talked about it so much, that a coworker who hadn't understood my drama addiction watched this & has been hooked on dramas ever since.

LONG LOVE LETTER - A LOVE TO KILL - CAN YOU HEAR MY HEART - HONG GIL DONG - THE SNOW QUEEN
I am such a crybaby when it comes to movies/dramas, so I basically cry almost to every sad ones.

But the one which made me cried my eyes out is without a doubt 1 Litre of Tears, Myu no Anyo no Papa ni Ageru, and Proposal Daisakusen
1 litre of tears :( autumn tale Boku no Hatsukoi wo Kimi ni Sasagu Koizora :( I had to cry so much in these dramas/movie
Stairway To Heaven ....emotional "trial-by-fire" drama of all time! Park Shin Hyde/Kim Tae Hee/Kwon Sang Woo/Baek Sung Hyun.

Sad Love Song
A Love To Kill
1 Litre of Tears


IMHO nothing lately ...be it 49 days, Scent of a Woman, Bad Guy, etc., compares.
one litre hands down. feet down. head down.
The ones that made me cry my eyes out while watching are Scent of a woman and Ima Ai ni Yukimasu.
