Hehehe..This can be a trick question, because most of the new and current anime is out sourced to Korea (The story/keyframes are done in Japan, but most of the animation is done in Korea), don't believe me, check the credits and you will probably see some Korean names.
about real korean anime, I do not know. I do not think there's that many..because anime has only 3% of the entertainment over there. That's why I'm so supprise about Wonderful Days. It was a major gamble because it is the biggest and most Expensive animation produced in Korea (being in the spot light). that's how I know about it. I do not know how the producers got the studio to do this, its like releasing an anime movie in theaters in the States ^^; (And we all know how these movies did).
Anyway, I'm also getting the DVD on Saturday as well and post a review of the subs. if its anything like the subs that's on the ripped movie on the net, then it's as good as any professional company can do :-)
About Korean Movie..if you can only see one Korean Movie..I highly recommend seeing "My Sassy Girl". You won't regert it!
