One of my nits is implications that Great Works require some sort of extra mental exertion. I've read many Great Works and it's not just that Crime and Punishment is better than As the Crawdads Sing <ugh> but it is also more engaging. People think that these books shouldn't be read without understanding Russian history or society and without careful comparisons of the best translations but it isn't necessary.
One of my mantras as a reader is that I no longer am in school and no one is going to make me write a paper or discuss overriding themes. I can read the way I like and enjoy what I like and if I missed all the mustard seed references than it doesn't matter to me.
I could go into a side discussion on how literature is taught but I'm sympathetic to English curriculum developers who have to give students some books to read and have some criteria by which they can make sure students have read and understood it.
