I’ll go first. Mine is the instant knockout drug. Like Dexter’s intramuscular injection that causes someone to immediately lose consciousness. Or in the movie Split where there’s the aerosol spray in your face that makes you instantly unconscious. Or pretty much any time someone uses chloroform.
Guns. Fuck me.
Guns don’t blow the user backwards, unless it’s a truly monster rifle fired from a standing position, and they certainly don’t blow the bullet recipient backwards. The first cowboy movies showed people dropping straight down when shot and audiences thought that unrealistic. Yes, that’s realistic and, I think, far more horrifying seeing someone’s strings cut. There’s a finality that showcases how deadly guns can be.
Rattly guns. Jesus. Guns don’t rattle you Nimrods. They might make tiny sounds here and there, but Hollywood guns sound like they left out some screws or pins after assembly. I have a Colt .45, a somewhat loosey-goosey design, can’t hardly get a sound even shaking the shit out of it. You can punt about any modern gun and not hear metal on metal.
Constantly cocking, racking, charging. Look! Here’s our super badass who’s been in danger the last 20-minutes, and he’s just now chambering a round?! Or, Mr. Badass has to charge his weapon, kicking out a perfectly good round, to show he means business! And if it didn’t eject an unspent round? Action hero was running around with an unloaded weapon. What’s funny is that a real badass would fire all but the last round and then swap magazines. No charging required! Yes, that’s way harder than it sounds.
My pet peve is people who insist I know how to disassemble an M14 blindfolded before my opinion about shooting children is valid.
(I know how to unload most guns, which is the only useful thing to do with them)
I know very, very little about guns. If a mistake is bad enough for me to notice, it must be truly lazy and terrible writing/directing.
