A saw someone comment in a forum about how movies are never as good as the book upon which they are based. I have a different opinion, and I guess that's what blogs are for, so...

Books are a completely different medium, and shouldn't be compared to movies. It's like saying Stephen King is better than Steven Spielberg. Both are great storytellers in their chosen area's but trying to compare them would be silly.

A book can convey a lot more information than a movie, because it is not time limited. So a movie has to try to tell the same story in a much shorter window. That means conveying things differently and leaving out a lot. If you are expecting a movie to have all the same content as the book, then you will always be disappointed. But if you make a conscious choice to not compare the movie to the book you can appreciate the movie for what it is and perhaps enjoy it more.
