Feel free to check out the article in the JoongAng Daily: New Subtitle Service for Korean Movies
Click here to view Cinus's pathetic English service website. I say pathetic because they don't put the movie times available in English... Or summaries for that matter... And I can't even check the movie times anymore on their Korean site, not because I don't understand, but because for some reason my computer won't process the hangul (just on their site) and all I can read is gibberish.
