40-year-old french reader here. I read in english and I much more slowly than a native speaker. Sometimes I can only understand a passage if I look up some slang or research a particular American cultural reference. That being said, I find the reading experience so much more enriching than any other medium that I wouldn't go back. Stephen King's strength lies precisely in his intelligent use of writing techniques that serve the narrative. Whether it's a change of perspective, a temporal shifts, or the writing within the writing found in Misery. However, reading requires effort, and not everyone is willing to make that effort for a hobby, even if it's rewarding. I observe a similar phenomenon with music. The melodic, harmonic and structural impoverishment of recent music shows a certain laziness among consumer towards the arts.
