That's interesting point of view. We are probably different, but as as a kid and young teen I didn't really analyze characters and plots much (different education system) and although I noticed some references and allusions, I didn't think about it deeper. When I later discovered "Tv Tropes" it opened my eyes and in way sucked lot of enjoyment from reading. I started noticing various plot devices much more and realized how much of what I read is derivative. Really ignorance is bliss.

I can't even say it has significantly benefited me. Most of what I read was rather trivial literature and even though it gave me good reading comprehension, I can't stop to wonder if it wouldn't have been better to for instance play sports and cultivate interpersonal skills, teamwork, discipline and hard work.
