I have to agree that McCraney can be quite long winded. But he's not a crap writer. He has so far been the best person I have read to explain and make many psychological concepts funny to learn and easy to understand. A little long-windedness is a cheap trade off.
I do respect and understand your opinion, I hate plabber-mouths myself. But you do other potential readers a disservice to say McCraney is a crap writer, when he is in fact a long-winded writer.
