The movie is better than the book

Rating: 10/10 (4 May 2008)

That's normally pretty hard to say, though the fact that the book is a Stephen King novella (150ish pages +/-) makes sense why the movie is better. Not bashing King here, just saying most of the movies based on his work tend to be pretty decent and novellas aren't meaty enough for my taste. Most the time when I finish a novella I wish there had been more substance.
As far as the movie goes, I'm sure everyone else has mentioned why it's so great. If you love this movie check out the book, they're pretty much dead on besides a few details. Unlike other novellas of King's e.g. Apt Pupil ... the extra details in that book made it so much better than the movie.
