(Most) Books contain relatively little violence, sex, and especially sexualized violence in comparison to TV and movies. When study after study has shown that what you consume affects how you think, I find this a huge point in favor of books. The amount that people are (and the amount that i have been) desensitized to violence today is insane.

I would say they also leave more room for plot development and concise endings. Most shows today drag on for season after season and don't have satisfying culminations. I've also seen very few movies that can make me think like a work of fiction can. Seeing the world through another relatable person's eyes can be a very profound experience.

Ignoring fiction or non fiction is a tragedy in my opinion.
