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.
I despise the “flashback to a thing that literally happened five minutes ago to make sure you connect that with whatever just happened/is about to happen.”
Total fucking turnoff. I’m here watching the show and I’m not an idiot. Flashback to something last season or a number of episodes ago? Fine. Some people need a reminder. Within the same episode? GTFO of here with that shit.
