For those who know where to look, it's out with good subs (there's also a shytty Google Translate subs version, stay the fukk away from that one).
I just watched it and it's very hard to progress what exactly I just watched. Mostly because it starts out as a really great and intriguing movie, and then like so many Korean movies, it takes such a twisted turn into something so far removed from its beginning that you feel part disappointed because you have this curiosity for what would have happened if it played straight while simultaneously keeping your eyes glued to the screen as the movie that's playing before your eyes is still every bit as brilliant as it can be.
One thing Bong Joon-ho absolutely nails here is the satirical social commentary. I think it'll play well for most audiences since class warfare is of all times and cultures, but as someone who's had his own experiences with South Korean culture, I can definitely say that Bong captures the social divide of the country perfectly. Of course it's assisted by brilliant camerawork and performances, creating that unique skin-crawling atmosphere only Korean cinema can pull off convincingly.
