From what do you learn more: films or text? Why?

Lets start from this particular example.

 OK! Being the same audience,how would I learn more about 'A Walk to Remember', from the print or the book? Obviously, I learn from the film more than the text. Films has multidimensionality, it has sound and motion whereas text lacks both. Audience require adequate attention to learn from texts versus films could virtually release audience from those requirement. Audience need a certain quality to decipher the textual meanings whereas films showcases ways of such denouement.
