I suspect it is not all that uncommon for someone who is not a native speaker of a language to enjoy the literature of that language more than many native speakers. The reason I say that is, for a native speaker, their own language isn't really anything novel. For example, it is extremely common here in the U.S. for most children to absolutely hate being forced to take English classes because "they already know English." This often extends to adulthood where they don't enjoy reading books, or any literature, at all. I personally respect anyone someone who takes the massive amount of time and effort it takes to read literature in a foreign language. It is a challenging and rewarding experience.
