Problem is, the concepts of “motion” and “growth” are not really compatible. You don't naturally think of one in context of the other. Also, the second tagline has no relation to the photo except for the book in the model's hands. (I have no problem with him, by the way. He looks a little like Sammy.) Cutting the tagline to read, “Set your life in motion: Read a book” would have made it cleaner and more relevant to the photo. But, committees. What can I say?
Anyway, the most fun thing about this ad, absolutely, is the staging of the shot.
