It kept my attention the entire way. I enjoyed the tempo of the film. This as many of Kings short story's had a common yet fresh way of developing the characters.
As in nonfiction story's rarely is life black and white. It's often very Grey. I enjoyed Craig's times with Mr. Harrigan.
I could emphasize very much in Craig's self imposed guilt about his mother's death. I also was able to emphasize with Mr. Harrigan as a character.
Good writing....
