I have seen Cabinet and I get what you are saying, esp by the scenery, but you should watch this film, you will see what I mean.
And how have you NOT seen Metropolis and have seen Caligari? Metropolis is probably one of the most influential films of all times. It is a definite must for any movie goer (which you are if you have seen Caligari haha)
But regardless of the influence we see from it, great video ehh?
I took a film class 2 semesters ago and Cabinet was one of the films we watched. I'll definitely check Metropolis out on Netflix if it's there. Anyways, the video rules.
