US remake

Here's something I thought I'd never say. This is a Korean film that could, gulp, benefit from a Hollywood remake.

It started out so promisingly, but didn't fulfill that promise. I'm not clever enough to explain what it was, maybe black comedy isn't a genre that the Koreans excel at, but this became a bit of a mess. However I could imagine a low to mid-budget remake with the right director (don't know who) making it darker and funnier.
