@pastanaga - I can kin of sympathize with both sides of it. I've been studying writing for a while and after I started it was difficult to enjoy a book because I'd always be looking for the flaws and finding dozens of them. They were things I'd never notice if I hadn't tried to be a writer myself.
But then I realized that I was kind of doing it wrong. I should be looking for the good stuff, not just the mistakes. Now I feel like I appreciate books more than I ever did because I can see more depth in them than I did before.
