Hollywood
Basically, any movie that's a "Chick-Flick" will depict silly, technically infeasible things when dealing with guns.
Two Examples:
1. In THELMA & LOUISE, the stars (girls) blow up a gas-tanker truck with 2 shots from their handguns (Right!). Huge red fireball -- all from their little ol' handguns! (Is it any wonder most women hate/fear guns... with "instruction" like this?)
2. In THE NET, Sandra Bullock fools the charming Hit Man on the yacht... by secretly removing the magazine from his Glock-19. Then, "expert" that he is, he FAILS to notice this (major weight loss) when he grabs the gun and tries to shoot her with it. And then, the "empty" Glock keeps going "click-click" as he tries in vain to shoot it! (Try that with YOUR Glock).
While "Chick Flick" is subjective, it probably applies to most movies which those posting here (male or female) would be moved to walk out on simply because of the blatant stupidity of the flick's use of firearms.
To test this, just go to the Internet Movie Data Base (IMDB) and click through the "User Ratings" of any suspicious movie. Invariably, such dumb movies will be rated about 0.5 to 1.5 points higher (1 to 10 scale) by females, especially in the younger demographic groups.
While it's no great revelation that Hollywood is extremely liberal, their utter disdain for us gun-toting Neanderthals in the Heartland often simmers just below the surface in their product -- and that attitude is rampant in the actual studios, production co's, agencies, and film schools -- which is why we get such cinematic crap that's essentially designed for the ballistically-illiterate Dumbed-Down ditz-teen movie market.
I can assure you that a writer, director, or producer who is (a) gun-smart, (b) has military experience, and (c) believes in the right of armed self-defense... is a very rare bird in any corner of the Hollywood system. Beyond that, such a filmmaker will be subjected to egregious discrimination and shunning. Just ask the dozen or so members of the "Hollywood Republicans!"
And I haven't even mentioned all those insipid "Gangsta" flicks where the super-cool ghetto-bangers shoot/spray their 9 mil hi-caps held horizontally. (Maybe it counter-acts gravity... or explains why their brains leak out of the heads as they strain to eyeball their horizontal pistols' sights.)
