What's your pet peeve when it comes to tropes? What bothers you when you see it in a show or a movie?
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.
People in zombie movies and shows that don't know what zombies are. I know it's so they can use cool descriptions like "the infected" or "walkers" or "the dead". The zombie word sounds kinda silly. But I still don't like it.
There might be trademark law involved with this. One of the creators like George Romero or someone might hold a trademark on the word "Zombie" for use in films.
I can tell you've never been to Baltimore in August.... You see a junkie slowly shuffling down the street wearing sweats in 100° weather... Zombies make a bit more sense.
