Oasis, the movie directed by Lee Chang-dong, is an incredible piece of work where you can see a very acute and tactful observation of the human condition. The kind that is brought on by the people in society who are forgotten and at the very end of the line. Scenery within the movie evokes emotions ranging from rage to sympathy, and yet you don't want to stop watching.
The story focuses on the retarded character Jong-du who was recently released from prison, and finds himself back at home amongst family who doesn't want him. Scenes show how as outcasted from family and society, not just for the way he acts but also his reputation. The crime in which he was involved (sort of) takes him to the victim's family, where he meets the physically disabled Gong-ju (Korean name for Princess).

What happens is they fall in love, but their relationship is of course not favored. However, you can't help but feel your heart swell when he makes the poor girl happy and imagine that she isn't disabled.
There is a lot intertwined in the plot of this movie and you realize that the misfit of the film is really just a victim of his family's shameful actions, along with the girl whose family takes advantage of her disability.
I don't want to give too much away, because not knowing key elements of the film, I feel are important to thoroughly enjoying this movie. That is why I highly recommend accessing it and giving it a try. It's not going to be a blockbuster-blow-your tv out, sort of movie. But will give you insight into the fringe side of Korea. Here's the trailer to get you ready:
