Example Input: Racist Classist Megalomaniac Talks A Little About Heroin . After hearing some decent things about this book, I was surprised at just how uninteresting and often offensive of a read it turned out to be.  Marlowe is accurate in some of her depictions of heroin use in the East Village of New York and way off base in others.  I chalk this up to everyone's experiences being different (however, I certainly don't think a one-bag-a-day habit with weeks off in between makes her an authority on addiction by any stretch of the imagination).  What I don't understand is why she felt the need to go into such great detail about her rather boring life between her discussions of the dope world.  Most of her anecdotes had little to no bearing on the story she was trying to tell and were mind-numbingly dull.  I found her narrative to be very disjointed and incoherent.  But what I found most repugnant was her better-than-thou attitude towards those of a lower class or darker skin tone (e.g. assuming dark-skinned men who didn't think to aspire to become more than security guards must not have gotten support or affirmation in their homes growing up, like she did).  She herself says that she became interested in street-life and street people in order to increase her "coolness" factor.  Sure she dabbled in drug use and in the East Village culture, but that does not make her an authority, and she does not paint a very true portrait of either.  If you want a good portrayal of street life and heroin use from the inside, read Seth Morgan's Homeboy.  If you want elitist drivel, this book should do the trick
Example Output: NEG

Example Input: Post-modern science fiction . Maybe I'm just not the right demographic for this novel, but I hated the beginning, tolerated the middle and put it down permanently near the end. The model is the Canterbury Tales of Chaucer, but I don't think it works. I just never got interested in the characters enough to care what happened to them and for me, the story--stories, really--never came into focus. I guess the New York Times Book Review should have tipped me off because they compare it to Frank Herbert's Dune and the Foundation series of Asimov, both of which, in my opinion have aged really badly. I never realized how bad Dune was until I saw the awful movie of it.    The fundamental metaphors operating in Hyperion seem to be backwards living. Well, ok, but I just don't see what it is a metaphor for. Nor, by page 473 where I finally gave up, did I care
Example Output: NEG
