This used to be true because most published books were well written. I don't think that's true anymore. Too much noise and too little signal so to speak. I feel a growing trend where books read like the author's main inspiration is TV shows, down to villains surprising the main character by jumping out from "behind the camera" and dialogue that reads like the book has no ability to convey thoughts and emotions except…
And I don't think only reading "quality" literature is necessary, you just need to not mindlessly read the same thing over and over again.
I've found my enjoyment of all media improved massively when I stopped trying to find what made it bad and started to look for what made it good.
Though some techniques start to feel cheap, like how fast food makes everything palatable by being crunchy salt and sweet.
