There is a level of predictability in King's book. He has a pattern in each of the three acts and he has become good in isolating incidents that make the act stand out. He is an incredible writer that way. 
 In 11/22/63, he breaks this pattern and writes arguably one of his best works. Though the story is based on a man traveling in time to late 50s, its less of science fiction and every bit human drama. He finds friendship: kinship that he hasn't felt in modern times, falls in love, dances like he means it and takes it upon to change history. 
 His observations are that of an ordinary man put in an extraordinary situation. There is drama, happiness, sadness, love, empathy, compassion, supernatural, creepiness, violent people, horrifying circumstances and the bleakness of a typical fictional town in King's universe. 
 If only it wasn't so long...
