I have three standout favorite dramas: Liar Game, Liar Game 2 and 1 Litre of Tears. It's really hard to pick, but I'm sure that Liar Game 2 is my all time favorite.
My favorite movie is Confessions.
there are close to 80 Japanese movies and Dramas on my list out of those I love Nodame Cantabile the most.
I found Tatta Hitotsu no Koi truly romantic
Risou no Musuko made me laugh a lot
Bloody Monday is my type of drama
Zeni Geba---just OMG amazing
Orthros no Inu was super cool
GOTH, very intriguing
and Norwegian Wood beautiful
Almost all my favourite dramas are J-Dramas anyway but so hard to choose just one...
But definitely ROOKIES, Nodame Cantabile, GTO (1998 version) and Hana Yori Dango
Fav Jdramas: Love Shuffle, Yamato Nadeshiko Shichi Henge, Hana Kimi, Majo no Jouken. Nodame Cantabile
Fav Jmovies: Ran, Seven Samurai, Time Traveler, Tokyo Girl, Koizora
Fav jdrama is a tie between Orange Days & Pride.
Fav jmovie ... there is one, but I'm not saying. It's not a film appropriate for anyone under age 18 so I won't mention it in a public forum.
