TrueNarnian, DO NOT go by the trailers that you have seen on TV to judge the movie as a whole. The actual movie is so much different than what they are advertising. I think they showed nearly all the CG scenes in the trailers, just not the complete scenes (they even showed the final scene of the movie in the trailer, which is highly unusual).
Other than leaving out my favorite emotional scenes (and one line that I think represented the turning point in the relationship between father and son: "Hell, ain't it?"), it was a good movie and good remake from the book.
