Both books and movies are really interesting. However, while books gives you free pass to imaginate and put faces to the characters, movies don't leave anything to the imagination.
Also, books are more extense when movies normally last 1'30 hour or 2 so a lot of information is cut out. Added to this, when you are reading a book you have to be focused on what is happening, but watching a movie you can be more relaxed. Conversely, at the same time you are reading you can be lost on your own world and still know what you are reading while if that happens when you are watching a movie you lost the plot.
In short, both books and movies are entertaining, so you can decide what you prefer depending on your mode.
