Cliches that you don't hate, but do bug you

[Sir Pootis]

I have two:

The first is less a cliche, but a quote: "Were not in Kansas anymore" is incredibly grating for me.

The second is the whole "Self aware android becomes kill-crazy" scenario. You'd think these scientists would put in some failsafes in case of this.

Don't judge me.

Happy endings, I don't mind them, but if they were less frequent then I would actually wonder how this film, show, book etc would end.

Holy fuck! Pedobear meets Lollipop chainsaw XD

OT:
"Lived happily ever after" stuff. Unless you kill of at least one main character by the end I don't like it as much. (and I HATE that "He died! - credits - Oh wait, he didn't!")

Main protagonist thats generally useless by himself. See couple first Harry Potter books and just about any harem romance anime as prime examples.

Kids outsmarting adult professionals. Unless they are about as "professional" as those burglars from Home Alone it usually makes no sense.
