Heh, I find the downvotes for the above comment amusing. 100% expected, but amusing. It would be pretty interesting to hear someone rationalize precisely why for example Deadhouse Gates is a worse book than Crime and Punishment :) .

At a guess, I would expect descriptors like non-serious (unlike serious C&P), a lowly fiction fantasy (unlike a documentary C&P, heh), suffering used as a vulgar shock content (unlike being a masterful depiction of a soul's torment in C&P), banal themes of isolation used as a dumb plot device (unlike Raskolnikov's isolation being a brilliant metaphor for an agonizing human psyche), a chaotic cacophony of disjointed narratives and different points of view (unlike a beautiful orchestrated suite of intertwining and supporting themes in C&P), a mindless pulp suitable for teenagers (and an intellectual feast for a curious mind hungry for a proper stimulation in a sea of drivel, in C&P).
