I was looking around also but couldn't find a place. They likely won't start showing Dogani with English subs unless it continues to stay popular and, if so, I imagine it'll probably take another month or two.
I broke down and decided to watch it without subtitles. With my limited Korean it actually wasn't too difficult to follow. I saw it on a date with a girl and lets just say it wasn't the best movie for that haha. Not that I was expecting it to be a good date movie but I enjoy dramas and thrillers that tackle social issues except it was kinda awkward when the girl next to me was pretty much cowering against the wall for the entirety of the film. Good movie, don't get me wrong, but don't expect it to be good date material. Some parts just make you shudder.
