Sorry, I can't find the thread where someone was asking for an easy movie to listen to in Korean.
I found one that seems like it would be pretty easy. I'm new and I could understand some of what was being said. The name of the movie is "A Moment to Remember". It is the story of a young woman with early Alzheimers who falls in love and gets married.
The dialogue is great for us who are learning Korean because the lead female actress often repeats her questions or thoughts, and no one speaks super fast in the film.
BTW. It's a great film and it's on-line at mysoju (the last link is broken, but if you go to YouTube and start around part 22 or 23 and view to 26, you'll be able to see the ending.)
