@Fiddle_Playing_Creole_Bastard—Then this video was made for you then. Enjoy.
.
My list includes:
-Main character saying, “What’s the worst that could happen?”
-Supporting female character will eventually run naked outdoors.
-The obvious killer tells the oblivious friends, “I am not the killer.”
-Any character within the first 7 minutes, “It could be any one of us.”
-Person answers the phone to nothing, but dead air – but will continue to say ‘Hello?’ for the next 16 minutes. Allowing the killer enough time to get inside the house unnoticed & possibly make themselves a hearty lunch.
-When a light doesn’t turn on the first time, maybe flicking the light switch another 48 times will make it work.
-An unimportant object falls to a loud crash & shatters across the floor. Just for the sake of having a sudden noise & action with no purpose.
-The sympathetic boyfriend is the killer & saves the beautiful girl for last.
-The dumbest character lands at least one blow on the killer. Whether they throw a high heeled shoe or awkwardly swing a fire poker at the killers spine.
I could do this all night, so I’ll stop here.
