I learned early on in life that I seldom agree with movie critics' assessments. What they tout as brilliant and ground-breaking, I often find creepy or boring. With a little thought, one can figure out the problem: movie critics see movies for a living and therefore enjoy experimentation and boundary-pushing. I, on the other hand, go to a movie for an evening's entertainment and just want to have a good time. We're looking for vastly different things.
Writers are the movie critics of readers. We've studied the process and know how it's supposed to be done, or at least we should. All too often, we see the hand inside the puppet, and it distracts us from the show. In addition, we know what's out there, and we recognize copycats with a yawn and a sigh. As a result, I often keep my opinions to myself these days when non-writing friends gush over this writer or that one. "Yes," I think to myself, "but she's so..." whatever it is I perceive about that author that I might not have objected to or even noticed in the past.
Reading a lot of books makes one a more perceptive reader (if one isn't just devouring them as an escape from housework or the aura of the commuter train). But writing books! Ah, there's the real measure. Those who write better appreciate the talent of authors who do it well. It may make one jaded toward hacks and pretenders, but inside a well-written book: how lovely is the dwelling place!
