What, doesn't it inspire you not to stoop to writing the same kind of drivel yourself? 
it has to be relatively well-written rubbish, otherwise i can't cope with it.
i mean, i might've been able to manage the claptrap of "the da vinci code", if it weren't for the fact his writing is utterly abysmal.
but i know what you mean. that's how i teach writing - i use ghastly examples to show people what NOT to do, cos if you're reading good stuff, you just glide through it, as it were. the best example is an "erotic fiction" site i found, which is so bad, it's painful. the students all fall about laughing at the atrocious writing, but it really illustrates what i drone on about, with regard to using appropriate imagery, visualising what you write, how to write dialogue, etc.
also, i'm trying to develop a more literary style at the mo, so i'm hoping that, if i read more "literary" works, i'll absorb it by osmosis.
reading "the piano tuner" by daniel mason, at the mo. stunning.
