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 agree with you! Also unhappy to say that cliffhangers might get more common. Movie makers learn they get more sales / rentals / subscriptions with cliffhangers: because then you’re invested & curious & HAVE to see the next one :/ hate it, but that’s capitalism
