Frank's hairstyle (minor spoilers)
Frank's hairstyle in the beginning confused me. The guy comes from Nam with pretty long hair. I'm not familiar with US army ranks, but (I suppose), he is a sergeant. As a veteran myself, I should ask, how could a sergeant (or whoever he is) have such long hair?
Same in the Prison scene. Frank comes out like freaking Elvis. I thought they shave your head in prison, don't they?
PS: Sorry for my broken English. I'm from somewhere else.
