I'm vaguely disappointed this isn't on Netflix.
I've been to that baseball stadium and watched the Doosan Bears play. Lots of fun things about Korean baseball, but until you've heard 5,000 fans singing "We're Not Going to Take It" in Korean after a bad call well... well, then... you haven't been to a KBL game.
That is the best thing I've read in a while. I don't feel like I need to watch the actual movie, but that was a great review.
