The Vietnamese storyline (Spoilers)
I really thought that added a great layer to the movie. It starts out all over-the-top with the guy's declaration that the Vietnam War is still on. Then we find out his sad backstory, seeing why he's doing what he's doing. His small cameo at the 'final showdown' was hilariously random and over-the-top, along with the rest of the scene. Then at the very end, Walken provides an uplifting, hopeful ending to the story which, for me, took me completely by surprise, and felt like it could have been its own little movie.
