I know. I'm supposed to be disappointed that it wasn't exactly like the book. That's how we lit. nerds and those "fan-boys" are supposed to, as my brother-in-law recently pointed out in conversation, assert our ownership of the material. It is also very (nauseatingly) fashionable to be hard on "prequels" or follow-ups to beloved movies. George Lucas knows this all too well.
Well, I was not disappointed that the movie was different than the book. Jackson and his team did what they needed to do. Remember, please, that this is a statement made by a guy who credits Tolkien and his work with changing his life. Tolkien's works set me on a path I walk until this day.
