Books are better in a sense. Technically, a book might be like a television series. You simply need more time to cover the material. Books are good for those who can read well enough. My mom said that the Wizard of Oz film gave her nightmares in the 1950's as she was growing up. Yes, books are better, overall. A lot of humans have been dumbed down. A movie is an interesting media for telling stories. However, it is not the only kind of media out there. Essentially, my comment here could be put in a book.

I saw Once Upon a Time, on ABC. It's a television series that went on for seven seasons and it featured some alternative story archs to the Wizard of Oz that I found very interesting.
