i suggest a movie that's coming on at Sunday on SBS, called Shiri.
well, let me review it... (i've got myself the DVD)
1) it's violent. obviously, guns are involves, with elite agents involved. which mean main characters don't die easily, but still bleed a lot.
2) it's about war and love. critics say it's 49% war and 51% love. why, don't ask me, look up on google.
3) it's good, from my personal experience.
if you can stand the blood and the violence, then you should definately see it. it does convey all the differences between North Korea and South Korea, although it's not to the full extent, it's good enough.
and believe it or not, this movie is rated G12+ in Korea. yes, The Matrix was rated G12+ as well. so if you're in Australia, i'd say you're looking at M15+ with violence and adult themes, if not MA15+.
