One of the things that tends to bother me the most about modern literary fiction (as with modern art) is the overabundance of vagueness, the heavy, heavy reliance on symbolism and whispy language. There is absolutely a lot of merit in using such techniques; no one appreciates being lectured on a particular subject, and so a certain degree of ambiguity in a work's theme is required in order to make it impactful. But it seems like a lot of time authors take it way too far, to the point that the message is so wholly buried in the vagaries of the work's construction that it's impossible to find, or worse yet, the author didn't even bother putting a message in there at all. Now, stories without a message are great, but the kind of 'stories' I have a problem with are those that do this and otherwise have no plot and no characters to speak of (only simple constructs to act as representations of something). This seems to relegate such works to nothing more than a curiosity, a puzzle that may be intellectually stimulating to try and solve but from which no truth can ever actually be derived, because the author never actually got around to putting one in. The modern art equivalent would be something like this; just pretty colors, supposedly representing some kind of raw emotion but otherwise thoughtless in design.
This seems to lead to countless essays or books or dissertations wherein people pick apart these works, grasp at any possible clue that might find to put together some kind of coherent message. The worst thing is when the authors of these deconstructions then go on to apply what they've learned to other, more clearly-written works (mostly older literature, i.e. Dickens, Flaubert, Dostoevski, etc.) and end up "discovering" new meanings that may or may not have actually been part of the author's original intent with the work. You'll note from the presence of such books as Family Guy and Philosophy (to give one of the more absurd examples) that this type of analysis can be applied to absolutely any work, no matter the author's original intent.
That's my opinion, anyway. What I'm wondering from the community is, what are your opinions on analyses like this? Does it matter if, when interpreting a work, most of what's gleaned ends up being a fabrication by the interpreter? Or maybe in simpler terms, what's the line between a useful truth and bullshit, or is there one? And do works that have no clear message and no clear story have a purpose other than mild mental stimulation? Is it lazy for the author to write something that's meant only to spark discussion about what it could mean?
