Here is another Korean that I enjoyed. No spoilers ahead, just a basic plotline. Several people from very different backgrounds find out that they have been chosen to be in a survivor-like tv competition. They're flown overseas and are taken into the desert by the director and his very small camera crew. The group is suspicious, but are distracted by the large black suitcase containing the prize money. The prospect of easy money brings out the best in some and the worst in others. Once the challenges begin, allegiances form and the weakest members are left to fend for themselves. However, the contestants soon realize that there is much more to this "game-show" than meets the eye.
Here is the trailer:
And here is part I with Eng subs, but don't know how long this link will last.
It can be difficult at times to find movies and dramas that don't follow the he's a rich jerk, she's a sweet but spunky orphan (terminal illness optional!), they hate each other, fight, fight, drunk piggyback scene, fight, fight, accidental kiss, he likes her, she sees his sweet side, in-law drama, blah blah blah. So when I do find one with English subtitles, it restores my faith in humanity. Boys Don't Cry (소년은 울지않는다, aka Once Upon a Time in Seoul) is a movie I really enjoyed (don't worry, no spoilers, just a basic plot-line).
