I submit that Hollywood has saved countless lifes on the street by promoting shooting from the hip, horizontal handgun, double horizontal handgun, under the armpit, double horizontal handgun, endless mags, Equilibrium Gramatton cleric gun-kata and all sort of similar Darwin filters, and insist that they continue.
Two things Hollywood has always refused to do: teach their actors even the most basic Russian accent when a non-native actor speaks Russian (they can learn 50 regional accents but not ten words in a different language - I don't buy it, hence it must be on purpose), and firearm realistics.
While I never understood the reasons for the former, there's deep logic for the latter.
