I think Korean directors have an incredible eye. Almost all Korean flicks I watch just look so damn good. Bloody Reunion is no exception. Aside from the unfortunate American title that is just too easy and obvious, this movie is a really entertaining ride. Well worth the watch.
Students get together, students argue, teacher demonized, really disturbing things happen (or do they). This has some good twists, and as is very common in asian cinema, a very BIG twist at the end.
