MOVIES; Sad Movie Koizora A Millionaire's First Love A Moment To Remember Haeundae (kinda. lol. this is a disaster film btw) Hello Ghost! Windstruck My Sassy Girl there are too many to mention :) :D DRAMAS: Let us all not forget School 2013 :) Wonderful Life Smile Autumn's Concerto
Hmmm....Old Boy, definitely, though it's a little disturbing, and White Christmas. And 1 Litre of Tears, and Soredemo, Ikite Yuku.
It really depends on your definition of deep, and your age, because what may be deep and meaningful to me as a 32 yr old woman, may not be to you.. but to me, deep is also thought provoking so here are two suggestions of drama's that really had me thinking afterwards: God's Quiz 1,2,&3 Akutou~Juuhanzai Sousahan
try 1 liter of tears and LIFE
Bambino when i was having a hard time with work before, it helped me a lot. with its words and stuff
The Chaser (I prefer the drama more than the movie) try it!
Scent of a woman. I don't watch tragedy kinda dramas but I like this one. Its not a complete tearjerker but had a small tinge of "feel" to it along with romance:)
