Oh, if Rightstuf were to sell Korean dramas...how much more of my money can our Dark Lord take? (I'd also like them to sell Japanese dramas, but I don't think, aside from a few exceptions like Animeigo, there are any R1 companies releasing J-dramas, and the ones that are being released are mostly, if not all, samurai related.)
In regards to K-drama, I'd recommend Dae Jang Geum. It is really fantastic, and it's the show my avatar comes from! For Japanese movies, I really liked Kamikaze Girls, which I found to quite funny. I laughed out loud several times during it.
