Loved the film, one minor nitpick
I really enjoyed the movie, I felt parts of it were influenced by Inglourious Basterds (in a good way), and Kang-Ho Song is always great to watch.
My one problem with the film, so to speak, is that it didn't provide much context for the resistance movement.
Why are the Japanese so bad? We don't see the Japanese police act barbaric to anyone except the resistance members it hunts down.
Why do Koreans want independence so badly? We don't even meet any Koreans who are not in the resistance. So we don't know what the average person's aspiration is.
What did their mission accomplish in the end? Without giving it away, their mission is only a stepping stone on the path to Korean independence, yet we aren't informed of the outcome.
These bigger picture questions were quite ignored, even in the opening and closing credits. So as a viewer mostly unfamiliar with the historical backdrop, it left me wanting more information.
