Nosferatu/YMMV

Ass Pull: One of the most famous in movie history; Murnau couldn't figure out how to kill Orlock, so he finally just said "Uh, sunlight? Yeah, that works..." Since then, every vampire in fiction has been vulnerable to it.
I Am Not Shazam: "Nosferatu" is another word for "vampire", but some seem to believe that it's actually Orlok's name.
Nightmare Fuel: For something nearly a hundred years old, this film has aged surprisingly well, especially in regards to Max Schreck's performance as Count Orlock.
Nightmare Retardant: in the opening scenes the villagers claim a werewolf roams thru the forest at night. The atmosphere is really creepy and the audience wonders what this creature will look like. When the protagonist goes to sleep the camera shows a wolflike creature walking in the forest, but it's clearly not a werewolf, left alone a wolf, but a striped hyena! And it's strange to downright ridiculous that this animal walks around in Transylvania, Romania.
- It could have escaped from a zoo or circus. It's happened before.
Soundtrack Dissonance: Some versions of the film feature a near-constant usage of a strange, cheerful little tune that sounds more like it would belong in an old Mickey Mouse cartoon than a classic horror movie. It becomes increasingly hard to get into the mood of the film when this song is in nearly every other scene, even in perfectly innocuous ones, such as the simple act of walking up stairs.
