Guilty pleasure: Karate Kid and Cobra Kai. I must confess that I am a huge Ralph Macchio fan (he is awesome in My Cousin Vinny, too). This autobiography provides red meat for fans like me, as the book mostly centers on the original Karate Kid film itself, focusing on the reason that the characters and themes have endured in such a powerful way and how these personal experiences have impacted Macchio's life. Easy, satisfying reading.
