Well , I always read books for the simple pleasure of reading
Then I took an English Literature course , and I can now spot plot devices and other things that I would never have noticed before. Does it enhance my pleasure of the novel? Not really , but it DOES help to appreciate the skills of the author
It may in time, however. The more good literature -- rather than reading matter written just to entertain -- you read, the more you'll find that the other stuff really does tend to be a lot less satisfying in the long run. Such techniques, coupled with genuine talent and skill, reach in and touch on a deeper emotional level, as well as intellectual levels. That's what makes such techniques worthwhile in the first place: they are things that have been slowly developed over very long period of time, honed and refined, until they resonate much more powerfully and much more profoundly, and in such a way that repeated readings only bring out more and more emotional depth as well as depth of thought.
And I can't say I've ever found reading
LotR "work" either; when I first read the book, I was twelve, and I simply enjoyed a good story, well told. It was only as the years went by, and I found myself drawn back to it time and again that I began to truly appreciate the truly amazing layers of levels in the thing; and, as I grow older, I find that the feelings it stirs tap into deep wells of experience and emotion, and reveal a great deal of insight and contemplation of such things in Tolkien himself. In contrast, I find that a lot of the more modern writing is, simply, quite shallow in comparison -- a lot of flash, but little or no substance. This is not true of all modern writers, by any means; and some can stand with the very best; but of modern literature in general -- especially genre writing -- I'd have to say it's a sound general statement.
Either way, though, I've never found it in any way difficult or laborious to read
LotR. (Now,
The History of Middle-earth is something else again; fascinating, but at times it is work. Worth it, but a much harder process....)
Again, I think the difference -- and it is one we're reluctant to address these days, it seems -- is that between genuine literature (or art) and (to use the phrase I put in above) "reading matter"... something written to entertain on a surface level; in other words, something to occupy the mind and kill time. Genuine literature, on the other hand, goes much, much deeper, and taps into a writer's innermost thoughts and feelings (though perhaps transmuted through the art of storytelling -- think of Lovecraft's racism becoming that extremely complex, powerful, and multilayered story "The Shadow Over Innsmouth") and therefore touches similar chords in a large body of readers. As I've said before, there's nothing wrong with pop-literature entertainment -- it does what it was created to do: to entertain. But -- save in rare, skillful hands -- it does little other than that. Genuine literature -- like genuine art in any other medium -- actually gives us deeper insight into the human condition, as well as our reaction to the world (and universe) around us; frequently challenging how we see these things forever after. At its very best, it can change the way we see them, and allow us to see (and enjoy) life much more richly and in more ways than we ever have before.
