When you read a story, you get to apply your imagination to the author’s storyline. You decide what the characters look like, the details of how the events described by the author actually play out, and what parts of the story to focus on.
On the other hand, when you watch a story in the form of a movie or show, you’re immersed in the director’s specific interpretation of the storyline. You have less room for variability in how you interpret a movie or show than a written story.
That’s one reason why I enjoy reading stories more than watching them. There’s certainly room for both, but the former lets you exercise your imagination and draw your own conclusions to a greater extent than the latter.
