Violence, gore, pornographic content and the like can be powerful things when used properly in cinema, and can help underscore an important point or to shock when well-placed. Melancholie der Engel is garbage of the highest quality simply because it has no placement and no subtlety in how it uses its arsenal of degeneracy and instead barrages you nonstop with stuff that is designed to disgust. There is no plot to speak of, just moments that dovetail to and from one another to create a new stage for something awful to happen.
I am not some conservative old man shaking my cane at the teevee for being "too lewd" or something, but I think that this movie needs to be destroyed and forgotten. This is like what a fourteen year old would create if given fifty thousand dollars and was told to make something "hardcore". Movies don't need to be art to be good, but this is neither and tries to be both.
