"Superfluous dialog"? At what point exactly. The entire film could be viewed as entirely superfluous given it has no distinct plot, which is probably due to the fact that it's based on the book by William S. Burroughs (who is known for his heroin-induced literary work). This isn't a film for mainstream crowds expecting Harry Potter or Transformers; this is a deeply visceral experience. This film will either make you feel awkward, confused, disgusted, or a combination of the three. That being said, it's not for everyone. People who have a taste for indie films might get something out of this. Otherwise, approach with an open mind.
