I 100% prefer watching movies over reading. Although reading can give you more information than a movie, I feel like movies are more entertaining & saves a lot of time. Some movies can be very disappointing though and reflect the book in a negative way.
I think between the two I really would prefer to read, just because authors can delve more deeply into scene painting and psychology while writing a book, whereas in a film a large chunk of that emotion can be lost in time constraints.
I also enjoy watching movies, mostly ones that makes me laugh. But I just find books more appealing overall.
