In a word, this film is fabulous.
It is an emotionally engaging, heartrending experience, essentially unlike anything I have ever seen before.
It is a shame that this movie remains relatively unknown--it is certainly comparable to some of the greatest "classic" films that people tout much more openly: the stark, unflinching way in which it addresses some of the darkest elements not only of our society, but of the individual, is unforgettable.
This is THE film for anyone who is looking for a thought-provoking, stirring, and unbelievably raw work.
Norton (who, incidentally, ended up contributing a great deal in the post-production process after the director effectively abandoned the project) delivers a fabulous and haunting performance.
NOTE: This film is not for everyone. Approach with an open mind, or stay away.
