For me the Army has ruined movies and TV forever. I was already a little irritated though that every gun has to do it's little clicky sound when the actor waves it around, every knife has to make a metallic swish when the actor waves it, and every time an actor is about to deliberately shoot someone they have to manually cock the hammer of their pistol.
I am particularly mad at FX for showing Archer firing an M16 with the safety obviously left on.
