Literature is like broccoli - when it's too dry, it's good for you but hard to swallow; and when it's too lip-smackingly delicious, it probably has lost most of its nutritional value. Is there an ideal balance between diversion and discussion? Can you be taught a valuable lesson without realizing it? What the hell is the redeeming social value of "Gone With the Wind?" See if you think the good people of Goodreads have achieved the happy medium between the pulpy and the penetrating.
