For me it's both! Why? In books there are a lot of benefits that we could get in there such us vocabulary worlds, relaxation, peaceful mind and can removes stress. This can also give us time to form our sleep because not all of us are easy to sleep. In movies, there are a lot of movie that being adapted from book. In movies, it is so easy to understand the flow, the plot, and the happenings into the book. The characters are moving, the settings are true, the situations or scence are easly to understands plus the story is being summarized. Both of them has the same benefits except for the vocabulary since the character can make adlibs.
