This is a rare instance in which the movie is much better than the original book, in this case a short story by Stephen King. Part of the reason for this is the wonderful work by Morgan Freeman in providing a voice over that sets the tone of the story and creates a special feel for the movie that is missing in the book. The acting by Morgan Freeman and Tim Robbins is good and creates a rooting interest for both their characters. The outcome is satisfying and creates an entertaining and memorable movie experience.
