I did end up getting to watch Gunpowder Milkshake after all. The movie theater added another showing so I could watch this movie at night.
Gunpowder Milkshake
I'm glad I got to watch it. It's an enjoyable action flick with heart. The action is innovative and brutal and I loved the aesthetics and the way they gave the movie an alternate universe out of time feel. 3.5/5
