These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Shadow Of The Vampire
Complete Monster: Orlock is just an animal looking to feast. Murnau is just... amoral.
Narm: Some of Schreck's expressions and gestures go over the top, mildly speaking.
Newer Than They Think: One of the chracters puts Murnau along with Eisenstein as one of the greatest directors of all time... despite Eisenstein not having directed any film yet in 1921.
Squick: Shreck plucks a bat out of the air mid flight, bites it's head off and drains it's blood. The look on his drinking buddies' faces says it all.
