Its the greatest form of entertainment IMO. Movies and theatre last a couple of hours, emphasis is on 'the look', story is usually (but not always) pretty shallow. TV is more episodic and therefore there's more time to explore the story but, again,its still pretty surface level most of the time. As streamers replace production companies and gain even more power, TV and movies are getting increasingly crapper. I read an interview with someone who worked for a streamer (wasn't Neflix but can;t recall which one it was and I can;t find the link now) who said the direction from bosses is producing content that is easy enough to follow if you're only half-watching. Sounds fucking awful.
Books, on the other hand, engage whole parts of your brain and quite literally take you into a different world. They can be quite short or very, very long - the edit is to fit the story, not making the story fit a prescribed length. Unlike movies or TV the only two people involved are you and the author - which is why I personally struggle with audiobooks as I feel like there's a third party (the narrator) involved who might interpret things differently than me. I've seen lots of great TV shows, plays and movies but I have never had as immersive an experience as I do with reading a book. I've never experienced an emotional response to a TV show or movie like I have from so many books. The feeling of knowing a character to their bones and loving (or hating) them is just impossible for me in movies/TV shows most of the time.
