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.
Most movies and TV shows are created these days with the assumption that people are on their phones at the same time. I mean actual studio notes to that effect when the plot becomes too difficult for the average person to follow when they have it on while they're also watching TikTok.
I get it. But I still hate it.
